The Life Cycle of a Foie Gras Duck (U.S. Perspective)

Foie gras production involves raising ducks under a specific regime to enlarge their livers for harvest. In the United States, only a handful of farms (primarily two large farms in New York, plus a couple of small producers) engage in foie gras farming1. Below is a detailed, step-by-step overview of a foie gras duck’s life from egg to slaughter, including industry-standard practices at each stage, expected living conditions, health issues, and welfare controversies. We also discuss why only male ducks are used for foie gras and contrast U.S. practices with those in other locations. Citations to credible sources are provided throughout for verification and deeper reading.

Foie gras ducks are typically a hybrid breed known as the Mulard (Moulard) duck, which is a sterile cross between a male Muscovy duck and a female Pekin duck23. This hybrid is favored because it gains weight readily and develops the large fatty liver desired for foie gras. Since Mulard hybrids do not breed naturally (they’re sterile “mule” ducks), farms maintain parent flocks or obtain fertilized eggs which are artificially incubated until hatching. Sexing and Culling: Upon hatching, workers separate the ducklings by sex. Only male ducklings are kept for foie gras – this is standard because males grow faster and their livers fatten to a higher quality (females tend to have smaller, veiny livers that are not as suitable)45. As a result, the female hatchlings are considered a byproduct. In France, for example, tens of millions of female ducklings are culled (killed) each year shortly after hatching, often by grinding (“maceration”) or gassing, since they cannot be used for foie gras4. (French foie gras producers have been exploring in-ovo sexing technology to end the mass culling of live females4, but traditionally the practice has been to destroy the females.) In U.S. farms, the same male-only policy applies; however, some producers have opted not to kill the females on site – instead, they ship the female ducklings to other growers (for example, to be raised for meat in other countries)6. For instance, one American foie gras farm in New York sends its female Mulard ducklings to farms in Trinidad to be raised for duck meat6. Regardless of destination, only the males continue on the foie gras track**. Brooding Phase: The male ducklings spend their first few weeks in a brooder phase. From 0 to ~4 weeks of age (the “start-up” stage), they are kept in large indoor groups with climate control7. Dozens or even hundreds of downy ducklings may be housed together on the floor of a barn or brooding room, often bedded with straw or wood shavings for warmth and comfort8. Heat lamps or heaters keep the area around 90°F for the first days, gradually decreasing as the ducklings grow feathers. During this time, feed and water are provided freely (ad libitum). The diet is a standard waterfowl starter feed (nutritious crumble or pellet), and the ducklings have constant access to water via drinker systems. This early phase is akin to how broiler chickens are started: the focus is on keeping the babies warm, clean, and well-fed to promote healthy growth9. The young ducks grow rapidly. By about 3–4 weeks old they’ll have begun feathering out. They are still much smaller than adults and require protection from cold and predators, so they remain indoors initially8. Mortality in this brooding period can occur due to typical issues in poultry (weak hatchlings, disease, etc.), but under good conditions most ducklings survive this stage. Notably, foie gras farms do not debeak or trim the bills of ducklings (a practice sometimes seen in other poultry industries) – Mulard ducks are not usually aggressive enough to require that, and the farms aim to minimize any practice that could damage the birds prior to liver fattening.

Around 4 weeks of age, the ducklings enter a juvenile or “growth” phase. In traditional foie gras farming (as practiced in France and elsewhere), this growth stage lasts roughly from week 4 to week 9 of life1011. At this point the birds can tolerate ambient temperatures and have a covering of feathers, so the farm may move them to more open grow-out housing. Housing: On some farms (especially in Europe), ducks are given access to the outdoors during the growth stage. For example, they might be kept in free-range enclosures or pasture during weeks ~4–9, where they can forage on grasses and insects in addition to eating provided feed1211. The idea is to take advantage of natural behavior: young waterfowl will gorge on available foods, and their esophagus (or “crop” area) will naturally expand – a physiological adaptation for migratory birds to store food11. Allowing moderate exercise and grazing is thought to keep the ducks healthy before the forced fattening period begins. However, in U.S. foie gras farms, outdoor access is often limited or nonexistent in the growth phase. Biosecurity and climate are factors – farmers worry that contact with wild waterfowl could spread disease, and in regions like upstate New York the weather can be harsh. One New York foie gras producer explained that they keep young ducks indoors to avoid exposure to wild-bird diseases, since the ducks are raised without routine antibiotics and are vulnerable to infections13. Thus, U.S. farms typically raise the growing ducks in large barns or sheds where they are sheltered but still in group settings. These barns are usually open warehouse-style structures with bedding on the floor (e.g. straw or wood shavings) and automated feeders and water lines hanging from the ceiling1415. The ducks can roam within the barn; they congregate in flocks and waddle around, able to stretch their wings and move about, though space may be somewhat crowded1416. Inside a U.S. foie gras duck barn during the growth stage: thousands of young Moulard ducks are raised together on a bed of wood shavings. Automated feeders (red units hanging from the ceiling) dispense grain feed. Ducks are generally kept indoors on such farms to protect them from weather and disease, though they have room to move, group together, and engage in some natural behaviors1413. Diet and Management: Throughout the growth phase, the ducks are fed a balanced diet to promote normal muscle and skeletal development (the aim is to have a healthy, fully-grown duck before fattening the liver begins). Typically, a grower feed (grain-based) is offered. In some production systems the feed is not totally ad libitum – farmers may restrict the time or schedule of feeding a bit during the later growth stage. For instance, they might feed the ducks at set intervals rather than allowing constant free-feeding11. This mild restriction encourages the birds to “competitive eat” when feed is available, which further enlarges the stretchy portion of their esophagus in preparation for the force-feeding later11. Aside from this, the ducks at this stage live similarly to other farmed ducks or broiler chickens: they eat, drink, socialize, and grow. By about 8–9 weeks old, a Mulard duck drake might weigh a few pounds. The birds are fully feathered and approaching sexual maturity (though these hybrids will remain sterile). No breeding behavior is needed or allowed – these ducks are solely raised for meat (foie gras, magret etc.), not reproduction. Living Conditions: The stocking density in growth barns varies. An industry claim from a U.S. farm was about 10 square feet per duck in the grow-out barn, but observers have noted the density can effectively be closer to ~5 square feet per bird or less in practice17. Photos from an American foie gras barn show a floor covered in ducks shoulder-to-shoulder18. There is a characteristic barnyard smell (ammonia from droppings) in these facilities19, though good farms add fresh bedding to reduce ammonia and keep birds clean. Unlike wild ducks, these ducks do not have access to swimming water – they typically only have nipple drinkers or small water troughs. Lack of open water to bathe or dunk their heads is a noted welfare concern (ducks enjoy bathing), and it can make it harder for them to keep cool in hot weather20. Fans and ventilation are therefore important in the barns. Overall, during the growth phase the ducks are relatively “normal” farm ducks. They can walk around, socialize, and are not yet undergoing any force-feeding. This phase lasts until roughly 8–9 weeks of age11 (around 2 months old).

Around 9 weeks old, the ducks enter a transition stage often called “pre-fattening” (or sometimes the “finishing preparation” stage). This stage bridges the gap between the free-growth period and the intensive gavage period. It typically covers ages ~9 to 12 weeks (about 63–81 days old)21. Diet Change: In the pre-fattening phase, the farm changes the ducks’ diet to one higher in starch (usually corn-based) and begins to introduce the concept of meals rather than continuous feeding21. The ducks might be moved back fully indoors if they had outdoor access, and their feeding becomes regimented. They are fed smaller meals at first, at set times, so they get hungry between feedings. Then gradually the portion size is increased and feeding frequency might increase as well21. This accustoms the ducks to eating larger amounts in discrete sittings, stretching their crop capacity further. Essentially, the farmers are priming the ducks to gorge. For example, one small U.S. foie gras farm describes that during the last 2 weeks on pasture, they give the ducks a fixed meal schedule to encourage the birds to “self-gorge” and stretch their crops naturally22. By the end of the pre-fattening stage, the ducks are eating a rich corn diet and have experienced periodic feeding – so the upcoming force-feeding will be less of a shock to their system. Housing and Management: During pre-fattening, ducks are usually kept indoors for increasing lengths of time23. If previously free-range by day, now they might be confined most of the day. They may still be in group pens or barn floors, but sometimes farms start using smaller pens at this stage. In some farming setups, ducks might be sorted into groups that will stay together during gavage. They continue to have bedding (straw) and room to move at least a few steps, but the space per bird may be reduced as they are prepared for the next phase. This stage might last 1–3 weeks. By the end of it, the ducks are typically about 12 weeks old and have reached nearly their full adult size (aside from the fattening). A typical Mulard drake might weigh on the order of 3–4 kg (6.5–9 lbs) at this point. The liver is still normal at this stage – it has begun storing a bit more fat due to the high-starch diet, but nothing extreme yet. All that is about to change with the final phase.

The climax of foie gras production is the gavage (force-feeding) phase, known in French as finition d’engraissement (“completion of fattening”). This is when the ducks are deliberately overfed to fatten the liver. In the U.S., this phase usually begins when ducks are around 12 weeks old (about 3 months). It lasts approximately 2 weeks for ducks on most farms2425, though some producers may extend it a bit longer with a gentler feeding schedule. By the end, the ducks are roughly 14–16 weeks old. Here’s what this phase entails: Special Housing: During gavage, each duck’s movements are restricted to make the feeding process efficient and avoid injury. In the past, foie gras farms used individual cages (called épinettes) that kept each duck confined alone in a very small space – often so small the duck couldn’t even turn around or stretch its wings. This is the image many have seen of foie gras: ducks with only their heads protruding from tiny wire cages, covered in corn mash and unable to move. Today, however, individual cages have been banned in the EU on welfare grounds26, and they are not used on U.S. farms either27. Modern farms use group pens or cages that hold several ducks together, or they may use larger individual pens that at least allow some movement. For instance, both major U.S. producers (Hudson Valley Foie Gras and La Belle Farms) tout that they are “cage-free” during gavage – meaning ducks are kept in small group pens on the barn floor or on elevated platforms, not in solitary cages2827. A typical setup in the U.S. gavage barn is a series of pens roughly 5ft x 7ft, holding about 8–10 ducks per pen29. Within these pens, ducks can huddle together and take a few steps or stretch, though space per bird is limited (on the order of 2–3 square feet per duck)1829. The pens often have slatted or wire mesh flooring instead of litter, so that waste droppings fall through and the area stays cleaner18. Overhead, there are typically large fans for ventilation and sometimes the pens are elevated off the ground. The ducks remain in these pens all day throughout the force-feeding period. Moulard ducks confined in group pens during the gavage (force-feeding) stage. In modern U.S. foie gras farms, ducks are kept cage-free in small groups rather than individual cages, but space is very tight – around 2–3 sq ft per bird30. The flooring is usually wire mesh or slats (visible here), allowing waste to drop through but causing discomfort and foot lesions as the ducks grow heavier31. Feeding Procedure: During gavage, each duck is force-fed a measured amount of high-energy food one to three times per day. The feed is almost always corn (maize) that has been cooked into a warm mash; often it’s corn boiled with fat (like cornmeal porridge), sometimes with added grain or additives to maximize energy32. Feeding is done using a long tube (20–30 cm long) attached to a funnel or pump, which is inserted down the duck’s throat to deliver the food directly into its esophagus and crop33. Traditionally, a farmer would pour the feed via funnel (gavage means “to gorge”) or use an auger; nowadays pneumatic pump systems are common. With a pneumatic pump, a feeding can take only 2–3 seconds for a duck – a pre-measured volume of corn mash is literally power-injected down the tube in a quick burst33. Skilled feeders can work very fast, moving from bird to bird down a row of pens. Each duck is usually grabbed (often the feeder straddles or holds the duck between their knees), the duck’s neck is gently stretched upward, and the tube slid down the throat. The feeder triggers the pump, delivering the bolus of corn. Then the tube is withdrawn and the duck is let go. On some farms, the duck might shake its head and waddle off, swallowing the food; on others, ducks may be more visibly stressed – individual reactions vary. This process is repeated for every duck, twice a day (on many farms) or sometimes three times a day on certain regimes3435. The amount of food forced into the duck increases over the course of the gavage period. At the start, a meal might be around 250 g (9 oz) of corn mash (dry weight) per feeding36. By the end, a single feeding might reach 400–500 g (if feeding twice a day) or smaller amounts if feeding more frequently – but overall up to ~1 kg of feed per day (dry weight) is given in the later stages3637. Because the mash is wet, the total mass is even higher (almost 2 kg of actual material including water per day)3839. Over 10–15 days of gavage, each duck consumes many times more food than it normally would. By design, this force-feeding exploits the duck’s natural ability to store fat in the liver. Waterfowl in the wild will gorge before migration, sometimes doubling their food intake and storing fat in the liver and body4041. Gavage pushes this to an extreme. Frequency and Duration: For ducks, the standard is two force-feedings per day (roughly 12 hours apart) for about 10–14 days total2425. Geese, being larger, are often fed three times a day for around 15–18 days24. There are some variations: The farm we toured (La Belle in NY) actually fed ducks 3 times a day for 25 days but with slightly smaller individual meals3435. Most French farms do a shorter schedule (approximately 12 days) with 2 feedings/day24. In either case, by the end of the gavage phase, the duck’s liver will have expanded massively. Ducks are typically ready for slaughter around Day 12 to Day 15 of force-feeding (when they are ~14–15 weeks old)42. At this point each duck has consumed perhaps ~20–30 pounds of corn in total. Effects on the Duck: The immediate effect of each feeding is that the duck’s crop (esophagus) and stomach are distended with a large volume of corn paste. Ducks do not have a gag reflex like humans (a duck’s windpipe opens on the tongue, not the throat, so they don’t choke in the same way)4340. The industry often points out that ducks can accept a tube without gagging or choking4440, and that their throats are lined with tough tissue (similar to our palms) that isn’t easily harmed by a smooth tube44. Nonetheless, the act of force-feeding is highly unnatural and stressful for the bird. Ducks typically struggle when being caught for gavage, and if the handler is not gentle, the insertion of the tube can cause bruising or small tears in the throat. Farmers are trained to avoid injury – for instance, modern gavage tubes are sometimes made of flexible rubber rather than metal to reduce damage45. In the best-case scenario, a duck will sit calmly through the feeding and waddle away seemingly “okay” afterward, aside from some head-shaking. In many cases, however, there is evidence the process causes pain or discomfort: researchers have found inflammation in the ducks’ esophagus and stomach lining after the first few force-feedings46, indicating irritation or injury despite careful technique. As the feedings continue, the ducks become lethargic and extremely obese. By the end of the gavage period, a foie gras duck has a liver that is 6 to 10 times its normal size47, weighing around 1 to 2 pounds just for the liver. This condition is essentially pathological – it is hepatic steatosis (fatty liver disease) induced by overeating48. The huge liver presses against other organs; it expands the abdomen and often makes it difficult for the duck to breathe and move normally4950. By the final days, many ducks have trouble standing or walking due to their engorged liver and overall weight gain. They pant more because of the fat burden and stress. Mortality and Culling: There is a significant mortality risk during this phase. Not all ducks survive until the scheduled slaughter. Studies have shown that between about 2% and 5% of ducks die during or by the end of the force-feeding period, which is much higher than normal duck-farming mortality. (In a regular duck meat flock raised to the same age, mortality might be ~0.2–0.5%)51. One scientific review reported mortality during gavage at 2–6%, higher than in non-gavaged meat ducks of the same age52. Ducks can die from ruptured livers, organ failure, or complications like choking or infections. Workers have observed that sometimes a duck “doesn’t get up, and it dies” after a feeding – one employee admitted there were times when 20 ducks died in a single day from the process53. The farm manager claimed their overall death stats were still within poultry industry norms54, but the risk of death is undeniably elevated by force-feeding. Those ducks that do die prematurely (or are too sick) are typically removed and discarded (not used for food). In summary, the gavage phase is an intense, high-stress, high-risk period for the ducks. It achieves the goal of a fatty liver for gourmet foie gras, but at the cost of the duck’s comfort and health.

After the roughly 2-week force-feeding regimen, the ducks are at the target condition for foie gras. At this point, the ducks are usually about 100 to 110 days old (3.5 to 4 months)42. They are swiftly sent for slaughter before their health deteriorates further. Transport vs. On-site Slaughter: In the U.S., foie gras farms often have on-site USDA-inspected slaughter facilities (both major NY farms do). This means the ducks are killed on the farm without needing long transport. In other countries, ducks might be transported to a slaughterhouse, but transport stress can cause additional mortality (foie gras ducks are fragile and prone to heat stress and even suffocation during transport55). Keeping it on-site avoids that and is more efficient for these relatively small-scale operations. Slaughter Method: Foie gras ducks are slaughtered in essentially the same manner as standard poultry in the U.S. The common method is “live-shackle” slaughter on a processing line56. Here’s how it typically works: Ducks are caught (usually at night or early morning when they’re calm) and hung upside down by their legs in metal shackles on a conveyor line56. The line moves the ducks to an electrified stunning bath – their heads are submerged in electrified water which is meant to render them unconscious by passing current through their body57. This is similar to how chickens and turkeys are stunned in slaughter plants. When done properly, the duck is knocked insensible. However, stunning isn’t always 100% effective; if the settings are wrong or the bird’s head isn’t fully immersed, some birds may be inadequately stunned (or not stunned at all). Immediately after the stun bath, an automated or manual knife cuts the ducks’ throats (severing the carotid arteries and jugular) to initiate bleeding (exsanguination)56. The upside-down ducks bleed out for a short period as they move down the line. This kills them via blood loss, ideally while they are unconscious from stunning. After bleed-out, the ducks’ bodies are dunked in a scalding hot water tank to loosen their feathers (the “scald tank”). Then mechanical pluckers remove the feathers. The carcasses are eviscerated (internal organs removed) and processed. A USDA inspector is typically present to oversee that the slaughter and processing meet hygiene and animal welfare regulations58. At one farm, for example, about 500 ducks were processed in a day, with a USDA inspector watching every step58. The farm noted the ducks were stunned in an electric water bath so they’d be unconscious, and then “air-chilled” after plucking to preserve meat quality59. Welfare at Slaughter: While this slaughter method is considered standard, animal advocates have raised concerns. If a duck is not properly stunned, it may be fully conscious when its throat is cut or when it goes into the scalding tank – meaning it could be boiled alive. Unfortunately, this does happen in poultry slaughter; for example, investigations have found instances of birds still conscious in the scald tank (resulting in drowning or scalding to death)56. Such mistakes are believed to cause suffering to a minority of birds at slaughter. Foie gras ducks, being quite weakened or unhealthy by slaughter time, might actually be easier to stun and kill (they’re often sluggish), but if they’re extremely fatty, the stun settings might need adjustment. After slaughter, the foie gras (fat liver) is the prized product – it’s carefully extracted and graded. Each liver is about 1–2 pounds and has a firm, fatty texture. Workers grade livers by size and the presence of any spots or damage60. The top-grade (“A”) livers are large and unblemished60. The duck’s other parts are also used: the breast muscles (“magret”) are a valuable by-product (often sold as duck breast fillets), the legs may be used for confit, the skin and fat rendered, etc. Essentially, the whole animal is utilized in gourmet products after the liver is taken. The lifespan of a foie gras duck is thus only about 3–4 months from hatching to death. (For comparison, a normal duck in the wild can live 6–10 years, and even a duck raised for meat but not force-fed might be slaughtered at 8–10 weeks for a petite duck or kept longer for specialty meat – foie gras ducks are kept a bit longer than typical meat ducks, but still a very short life.)

Foie gras production is highly controversial due to animal welfare concerns. The process of force-feeding ducks to intentionally induce a diseased state (fatty liver) raises serious ethical and health questions. Below we outline the common health problems and signs of suffering that ducks may experience, based on veterinary studies and investigations: Pathological Fatty Liver (Hepatic Steatosis): By design, foie gras ducks develop massive fat accumulation in the liver – the liver may reach 10 times its normal size49. This impairs the liver’s normal function (blood flow through the organ is obstructed) and can lead to liver failure if continued61. The enlarged liver pushes on the lungs and other organs, making it difficult for the duck to breathe properly in later stages50. Ducks often become inactive and reluctant to move because of the distended abdomen. If the force-feeding were extended longer than it is, the ducks would likely die of liver failure or related complications – in fact, death will occur if force-feeding continues until the liver ruptures or stops functioning61. Esophagus and Throat Injuries: Repeated insertion of the feeding tube can cause trauma to the throat and esophagus. Even with careful technique, researchers found evidence of inflammation and lesions in the upper digestive tract of force-fed ducks – e.g. esophagitis (inflamed esophagus lining) is documented during the gavage period62. Some ducks suffer small tears or wounds if the tube scratches them, and there is a risk of aspiration (food entering the airway/lungs). If corn mash accidentally gets into a duck’s lungs, it can cause aspiration pneumonia, which is often fatal if not caught. Choking can also occur if too much feed is given too fast, although pneumatic systems are calibrated to avoid outright suffocation. Stress and Behavior: Being grabbed and force-fed is undoubtedly stressful for the duck. Ducks typically exhibit avoidance behavior – they try to move away from the person who does the feeding, and some struggle against the process6364. Animal welfare scientists note that ducks show aversive behavior toward the force-feeder, indicating they fear the process65. Investigators have videotaped ducks frantically trying to escape in cage systems when the feeder approaches. Even on “humane” farms, the ducks will shy away when a human enters, which is natural for waterfowl. Industry defenders counter that ducks naturally avoid humans in many cases; for example, 4-week-old ducks that have never been force-fed will still scatter when a person comes near, so they argue that avoidance during gavage isn’t necessarily learned but innate66. Nonetheless, it’s clear the ducks do not enjoy being handled for force-feeding. Scientists measured stress hormones (corticosterone) in force-fed ducks and found a spike during the first few feedings, though interestingly after a few days the hormone levels during feeding dropped closer to baseline – suggesting ducks might acclimate to some degree67. (Handling itself is stressful to them regardless.) Still, the overall welfare during gavage is considered very poor by independent experts2068. Mobility Problems: As the ducks gain extraordinary amounts of weight in a short time, they often develop posture and gait abnormalities62. They may have difficulty standing up or walking; many spend much of their time lying down especially toward the end. The combination of obesity and an overgrown liver can cause lameness. Additionally, the conditions in gavage pens contribute to leg and foot issues: ducks are kept on wire or slatted floors without bedding, which can cause painful footpad dermatitis, sores, and even foot or leg deformities6231. Contact dermatitis (sores on the skin where it contacts rough surfaces) is “widespread and often severe” in foie gras ducks according to a welfare review62. Some ducks also get breast blisters or lesions on their keel (breastbone) from lying on hard surfaces with extra weight. Broken bones can occur too – for instance, in overcrowded cages ducks sometimes injure wings or legs. Undercover footage from European foie gras barns documented ducks with broken and bloody beaks, and birds with injured wings, likely from rough handling or desperate flapping in tight cages69. Respiratory Issues and Overheating: Ducks undergoing gavage often show signs of respiratory distress – panting and open-mouthed breathing. This is partly because the enlarged liver compresses air sacs and lungs, and partly because of stress/heat. If ducks cannot immerse in water, they also struggle to cool themselves. Panting ducks have been observed especially in warm weather. Some reports mention heat stress killing force-fed ducks if barns get too hot70. The inability to properly bathe (only having minimal water) can cause poor feather condition and makes cooling difficult20. Disease and Infection: The conditions and physiological stress of foie gras production predispose ducks to certain illnesses. Overfed ducks often develop diarrhea (their droppings are loose due to the high-fat, high-quantity diet). The wet droppings and warm barns can foster fungi and bacteria. Ducks in foie gras barns have been known to contract aspergillosis (a fungal infection in the respiratory system) and candidiasis in the digestive tract71. Liver dysfunction can weaken their immune system. Some veterinary literature also notes the risk of secondary infections – for example, if a feeding injury occurs, infection can set in, or if the liver’s function is impaired it can lead to systemic issues72. One common problem is bacterial infection in the throat or liver due to the unnatural feeding; another is amyloidosis, a condition where chronic stress on the liver causes protein deposits that can be harmful (some research even raised the question of whether humans eating foie gras could ingest these proteins that contribute to disease)73. Mortality: As mentioned, mortality rates are much higher in force-fed ducks than in normal ducks. Even farms with the best care have a few percent of ducks die from complications. A French veterinary review concluded that “steatosis and other liver changes…can limit duck survival” – meaning the induced fatty liver itself is life-threatening to the animal62. If force-feeding went on too long, 100% would eventually die; the only reason mortality isn’t higher is that they slaughter the ducks at the brink of liver failure. One foie gras farm manager noted about 4% of his ducks die before slaughter74. In contrast, a well-run standard duck farm might have only 1% mortality to market age. The elevated death rate is a clear indicator of suffering: ducks sometimes literally eat themselves to death under gavage. In sum, from an animal-welfare perspective, foie gras production causes significant suffering and medical issues for the ducks. The ducks are intentionally pushed into a state of severe hepatic lipidosis (a disease state) and endure force-feeding that can injure and distress them. The European Union’s Scientific Committee on Animal Health and Welfare has stated unequivocally that force-feeding, as practiced for foie gras, is detrimental to the welfare of the birds72. Animal rights and welfare organizations (HSUS, PETA, Humane League, Four Paws, etc.) universally condemn the practice as cruel7576. Graphic exposés have shown ducks panting, bleeding, and struggling in foie gras farms69. There is essentially a consensus among independent veterinarians (outside the employ of foie gras companies) that force-feeding causes very poor welfare and should not be practiced20. Indeed, a 2017 review in the journal Animal Welfare concluded that given the range of injuries and maladies observed, “force-feeding causes very poor welfare in ducks”20.

The foie gras industry, especially in the U.S., has pushed back against cruelty allegations by arguing that ducks do not suffer as much as people assume. They highlight certain physiological facts and farm practices in an attempt to show the process can be humane or at least not torture. Here are the key points often made by producers and supporters, along with how they implement welfare measures: Anatomy Adapted to Gorging: Producers note that waterfowl naturally lack a gag reflex and have a different throat structure than humans43. A duck’s trachea (windpipe) opens in the tongue, so when a feeding tube is in the esophagus, the duck can still breathe and won’t choke43. They also emphasize that a duck’s esophagus is lined with tough, keratinized tissue (unlike the soft human esophagus). This allows ducks to swallow whole, live fish with spines without injury – so, farmers argue, a smooth feeding tube does not injure the duck’s throat in the way we might imagine if it were a human throat44. These physiological adaptations are cited to claim the ducks don’t feel pain from the tube insertion itself. Natural Capacity for Liver Fat: It’s frequently pointed out that migratory birds naturally undergo hepatic steatosis seasonally – storing fat in the liver as an energy reserve for migration77. Foie gras is essentially forcing this process. Importantly, foie gras advocates claim that the fatty liver in ducks is “a normal and reversible process” for them41. They note that if you stop force-feeding, the liver will usually return to normal size after some weeks (and indeed studies have shown the condition is reversible in early stages). They contrast this with mammals, where a fatty liver is always pathological – in waterfowl, a fatty liver is part of survival strategy. While true to an extent (wild ducks do fatten their livers by perhaps 50% in the wild), critics respond that the foie gras liver (up to 10x normal size) far exceeds natural ranges and is clearly pathological by that point49. Feeding Amounts and Voluntary Gorging: Farmers claim they do not actually give the ducks more in a single meal than the duck might eat on its own if it encountered abundant food. For example, Hudson Valley Foie Gras asserts that ducks in the wild can eat up to 750 g of food per day when fattening naturally, and on their farm the ducks are fed about that amount (split into meals) – no single gavage meal (≈250 g) exceeds what a duck might voluntarily consume at one time78. In other words, they argue the ducks’ crop capacity is not being overfilled beyond its natural limit; they’re just ensuring it’s full every time, multiple times a day. This argument is somewhat semantic, as the duck probably wouldn’t choose to keep its crop constantly stuffed 2–3 times a day for two weeks, but it’s meant to counter the image of “exploding stomachs.” Training and Caretaker Bond: At least on the larger U.S. farms, workers who do the feeding often are assigned to the same ducks throughout the cycle to reduce stress. Ducks can recognize individuals; one farm found that ducks got used to the feeder’s presence and were calmer, and they even tried using two feeders wearing the same clothes (same scent) to see if ducks would accept a second person – they did, suggesting it’s the familiarity that matters, not the particular person7980. Farms say their feeders are trained to be gentle and calm. Industry reps sometimes claim that ducks will “queue up” to be fed or at least not run away. (The reality observed on a farm tour was that while ducks did not appear extremely panicked, they certainly did not eagerly line up for the tube – they simply tolerated it without extreme panic in that setting81.) Cage-Free and Group Housing: Modern foie gras producers (especially under public scrutiny) emphasize that they have eliminated the cruellest confinement methods. As mentioned, individual cages have been phased out on reputable farms27. Hudson Valley Foie Gras publicized that its ducks are maintained in social group pens with room to move, interact, and exercise (within reason)2882. The farm touts providing conditions for “freedom of movement” and reduced stress by keeping ducks cage-free during gavage28. Indeed, videos from some U.S. farms show ducks in small groups on straw or wire flooring, able to move a bit and flap (unlike the horror of tiny individual wire cages shown in old European footage)2882. This is a welfare improvement, though critics note the space is still extremely limited (2–3 sq ft per duck)18 and the ducks still cannot perform many natural behaviors. Improved Feeding Equipment: Some farms have adopted softer, flexible feeding tubes (instead of rigid metal) to minimize injury4583. La Belle Farms in NY, for example, uses a custom flexible plastic tube, which they believe causes less irritation. The feeding machines are calibrated to stop if resistance is met, and feeders are taught to feel the duck’s neck for any food remaining – if a duck hasn’t digested the last meal, they skip that duck’s feeding to avoid overloading it84. These practices, the farm claims, ensure that no duck is forced beyond its capacity (they physically can’t take more than their crop can hold)84. It’s in the farm’s interest health-wise, too, because overstuffing could cause aspiration or death which they want to avoid. Veterinary Oversight and Low Morbidity Claims: Producers often have veterinarians monitoring the flock’s health. They claim that aside from the intended liver fattening, the ducks remain healthy. Marcus Henley of Hudson Valley (who is ironically a vegetarian farmer) has invited journalists to “see for yourself” and claims you won’t find evidence of suffering85. In one account, a visitor noted the ducks “indicated much besides indifference” during gavage – they didn’t visibly struggle much once being fed8586. Farms like HVFG have used those observations to assert that “few adverse effects are evident” during gavage, aside from the ducks becoming sedentary72. The American Veterinary Medical Association (AVMA), which tends to align with livestock industry perspectives, has stated that in foie gras ducks “few adverse effects are observed” in well-managed operations, but the AVMA does acknowledge there are welfare risks like respiratory infections and locomotor problems due to obesity72. (This lukewarm AVMA stance is often quoted by foie gras proponents as “even veterinarians say it’s not so bad.”) It should be noted that even when best practices are followed – cage-free housing, careful feeding, veterinary care – the foie gras process still results in a diseased, dying animal by design. So the debate is whether these measures meaningfully reduce suffering or simply put a gloss on an inherently cruel practice. Animal welfare scientists remain unconvinced by humane claims. For example, the Cambridge 2017 review pointed out that even in group housing, ducks had to be trapped with crowd gates, showed fear of the feeder, and had high incidence of injuries and illness6220. The industry’s improvements (like flexible tubes and no cages) likely do mitigate the worst pain (fewer throat injuries, less extreme confinement), but they do not eliminate the core issue: force-feeding to extreme obesity. In response to the controversy, some farmers and researchers have even explored alternatives like “natural foie gras” where ducks or geese are not force-fed but allowed to gorge themselves in autumn (more on that in the next section). There are also culinary professionals who argue that foie gras can be made humanely or at least with minimal suffering by ensuring ducks are well-treated until the last moment. Chef Anthony Bourdain, after visiting a foie gras farm, famously defended the process, saying the ducks were not miserable as activists claim87. Nonetheless, due to the fundamental act of gavage, foie gras remains one of the most criticized animal products on ethical grounds.

Foie gras production varies somewhat by country and species, even though the basics are similar. Below we contrast how foie gras ducks (and geese) are raised in different locales and note legal or cultural differences: United States: As discussed, the U.S. has a very small foie gras industry – roughly only two major farms produce about 90% of U.S. foie gras (Hudson Valley Foie Gras and La Belle Farms, both in Sullivan County, NY), together raising an estimated ~300,000 ducks annually1. There are perhaps one or two very small artisanal producers accounting for the rest (e.g. a farm in California prior to the ban, or a newer farm in the Midwest or South). U.S. production is exclusively duck foie gras; no geese are used for foie gras here. The U.S. farms tend to be vertically integrated (breeding their own ducklings through processing)88 and use modernized methods: group pen housing, no individual cages27, and some technological tweaks (like plastic feeding tubes, etc. as noted). Ducks in the U.S. are generally kept indoors (barn-raised) rather than free-range, due to climate and disease concerns13. Culturally, foie gras is not common in American cuisine, and the industry markets it as a luxury niche item. The U.S. farms have faced heavy activism, and there have been legal battles (California banned foie gras sales from 2012–2015 until a court ruling allowed out-of-state foie gras to be purchased by individuals89; Chicago briefly banned foie gras in 2006–2008). New York City passed a law to ban foie gras sales in restaurants in 2019, but it was struck down by state authorities in 2022 before it could take effect90. Thus currently, foie gras production and sales remain legal in most of the U.S., except California (which bans local production and sales in restaurants)8991. The small scale of U.S. production means any differences in practice can vary farm by farm. Both major U.S. farms use Mulard ducks and very similar techniques, learned originally from French foie gras experts. One difference from France is what is done with female ducklings – as noted, French hatcheries cull females, whereas the NY farms claim to send females to other uses (this might be a self-imposed practice to avoid bad publicity). France: France is the world’s largest foie gras producer and consumer by far – as of a few years ago France alone produced about 70–75% of the world’s foie gras (over 14,000 tons in 2020)9293. Foie gras is deeply embedded in French cuisine and even legally protected as part of “cultural and gastronomic heritage” in France9495. There are thousands of foie gras farms in France, ranging from small traditional family farms to large industrial operations. About 96–97% of French foie gras is from ducks, and only ~3–4% from geese9697. The breeds are the same (Mulard ducks for the vast majority, with some Muscovy; and Landes geese or others for goose foie gras). Traditional French production often involves more outdoor rearing: ducklings are brooded indoors 4 weeks, then raised in outside yards or fields from 4–9 weeks (weather permitting)1211. The ducks might roam orchards or fields during the day and are herded into barns at night. This free-range period is part of the Label Rouge traditional methods. Then the ducks are brought in for pre-fattening and gavage similarly to elsewhere. Historically, individual cage gavage was common in France (tiny wire cages where each duck could only stick out its neck). This was heavily criticized. In 2015, France implemented new minimum standards that effectively banned single-bird cages and required at least group pens where ducks can spread their wings and turn around2665. Now French farms use either small group cages (e.g. 4–5 ducks per cage) or larger pens on the floor. Still, footage from some French suppliers in the 2010s showed awful conditions (ducks in small cages, injured and filthy)69 – there can be significant differences between farms. The best farms have spacious outdoor runs pre-gavage and only use gavage for ~10 days at the end, with ducks in cleaner group pens. The worst still had near-industrial confinement. France also has breeding operations to supply ducklings (hatcheries where the female culling occurs on a huge scale, as noted ~10 million females shredded per year in foie gras sector98). Foie gras being a traditional product means French law mandates that only liver fattened by gavage can be labeled “foie gras” – this discourages alternative methods99. There is also a strong political lobby defending foie gras in France. Nonetheless, public opinion in France has been shifting; polls have shown a significant fraction of French citizens would support banning force-feeding on welfare grounds100. Hungary, Bulgaria, and other European producers: Hungary is another major producer (especially of goose foie gras). In fact, Hungary and Bulgaria supply a lot of the world’s goose foie gras. These countries typically use similar methods to France. Hungary produces millions of Mulard ducks and some geese for foie gras (though the practice has faced scrutiny and some temporary bans due to bird flu outbreaks, etc.)101. In general, geese are more commonly used in Hungary than in France; goose foie gras is considered a delicacy (often a bit larger, different flavor). Geese are usually gavage-fed for longer (~3 weeks) and often by hand or funnel (some smaller farms still do it by hand without pneumatic pumps). Geese are stronger and can be more difficult to handle, but they also have perhaps a calmer disposition in some cases. The welfare issues for geese are similar to ducks – force-feeding causes the same liver condition and issues. Geese do have an advantage that they naturally do undergo extreme liver fattening for migration (even more so than ducks), but again not to the extent foie gras does. Many Eastern European farms, like in Bulgaria, supply raw foie gras to France for processing. These farms often faced criticism in EU audits for poor conditions. Spain (Ethical Foie Gras experiments): Notably, a farm in Spain (Extremadura region, by farmer Eduardo Sousa) gained fame for producing so-called “ethical foie gras” without force-feeding. There, geese are allowed to roam freely and naturally overeat on figs and acorns in the autumn, just as they would before migration102. The geese liver fatten to a certain extent on their own. Sousa then slaughters them at the peak of this natural fattening (right before migration when the liver is fatty, though not nearly as large as gavage foie gras)102. This product won an award and is marketed as foie gras from non-gavaged geese102. However, French law doesn’t recognize it as “foie gras” since gavage wasn’t used, so it’s often sold under names like “ethical foie” or “fatty goose liver” rather than foie gras in France103. This method is far less efficient – it yields a smaller liver and only works seasonally with geese (ducks don’t naturally gorge as extremely as geese do for migration). Thus, it remains a tiny niche. Some other Spanish producers and a few in other countries have tried similar methods or extended feeding periods to claim a more humane foie gras. These alternatives are still rare and controversial in terms of quality differences104105. Global Bans and Different Approaches: Several countries have banned foie gras production outright on cruelty grounds. For example, the United Kingdom, Australia, Germany, Italy, Norway, Poland, Turkey and others forbid force-feeding birds (so they cannot produce foie gras)106107. In some of these countries, foie gras (produced elsewhere) is still legal to import and sell; the UK, for instance, doesn’t make foie gras but imports it (there have been pushes to ban imports too). India took the step of banning not just production but also importation of foie gras107, effectively making it foie-gras-free. Within the EU, only a handful of countries still allow force-feeding (France, Belgium, Hungary, Bulgaria, Spain as of the late 2010s)106. Others, like Austria, Czechia, Denmark, Finland, etc., have banned it. Even where it is legal, some retailers choose not to carry it due to public pressure108. California’s ban on sales (enacted in 2012) was one of the highest-profile in the U.S., though as mentioned it’s been partially circumvented by allowing personal orders from out-of-state89. Duck vs. Goose Foie Gras: Historically, foie gras was made from geese (the practice dates back to the ancient Egyptians and was adopted in Europe, with geese being the primary animal)109. Today, ducks have largely replaced geese because they are cheaper to raise, easier to handle, and their foie gras is slightly less fatty (some say more “consistent”). About 95%+ of foie gras globally now comes from ducks297. Goose foie gras is still produced mainly in Hungary and to a lesser extent in France (Alsace and some farms in southwestern France keep geese). The differences in practice: Geese are bigger and can eat more, so they usually get 3 smaller meals a day vs 2 bigger meals for ducks24. Geese also require a longer rearing period (often slaughtered at ~16 weeks vs 12–15 for ducks)42. Geese can be more expensive to feed because they eat more. In terms of welfare, geese may actually suffer similarly or even more in some respects – their larger size meant in the past they were often confined in individual cages just like ducks. But group housing is also used for geese now. Some anecdotal reports suggest geese might be slightly less panicky than ducks during gavage (possibly because they’re domesticated in a different way), but it’s hard to generalize. Both ducks and geese on force-feed regimes develop the same pathological liver changes and health issues62. One notable difference: female geese are not culled at hatch for foie gras – since geese are not sexually dimorphic in liver development the way the hybrid ducks are, female geese can be used for foie gras too (so goose foie gras farms typically raise both ganders and geese). In duck foie gras, recall that only males are used, so that aspect is different. Product and Taste Differences: Some gourmands note that goose foie gras has a slightly more delicate flavor and smoother texture, while duck foie gras is a bit more robust and gamey. Goose livers also tend to be larger (an average goose foie gras liver might be 600–900g, whereas a duck’s is 400–600g). However, due to cost and the decline of goose farming, most foie gras on the market is duck, and many consumers can’t tell the difference once prepared. In summary, location plays a role mainly in scale and regulatory environment. French foie gras ducks might spend a bit more time roaming outside early on and are part of a huge traditional industry, whereas U.S. foie gras ducks are raised entirely indoors but in a very limited number of facilities. Welfare regulations are stricter in the EU (no individual cages, etc.), but U.S. producers have largely followed suit voluntarily to avoid backlash. Some countries outlaw the practice entirely, considering it inherently cruel. There are niche “ethical” producers trying longer, non-force methods, but these remain rare. Foie gras, whether from a small artisanal Spanish farm or a large French factory farm, ultimately relies on the same principle of liver steatosis. Thus, while the duck’s life from egg to slaughter may be marginally better on one farm versus another (more room, less stress, or shorter gavage period), the core experience (especially the final weeks) is fundamentally similar across locations – with the duck’s welfare being severely compromised for the sake of a luxury food product.

A foie gras duck in the U.S. lives approximately 15 weeks from hatch to slaughter, experiencing a fairly standard poultry rearing for the first 8–10 weeks, followed by a dramatic forced-feeding regimen that causes extreme liver enlargement. Throughout its life it can expect to be kept indoors (in U.S. farms), on bedding at first and later in tight quarters on wire flooring. It will never mate, nest, swim, or fly; its female siblings were removed at birth. In the final two weeks, it will endure twice-daily force-feedings, gain an enormous amount of weight, and likely suffer various maladies (from difficulty breathing to leg pain). While producers provide food, shelter, and veterinary care, and insist the ducks aren’t tortured in the worst sense, the process inherently involves cruelty by modern animal welfare standards. As numerous sources and expert analyses document, the life of a foie gras duck is one of being used as a means to an end – with industry “standard practices” pushing the animal’s body to a pathological extreme to obtain a fatty liver delicacy6275. Sources: The above information is drawn from a range of credible sources, including scientific welfare reviews (e.g. Rochlitz & Broom 2017 in Animal Welfare110), investigative reports by animal welfare organizations69111, on-site journalism accounts (e.g. Modern Farmer visit to Hudson Valley Foie Gras17112 and Serious Eats visit to La Belle Farms11329), statements from foie gras producers themselves4443, and government/industry data (e.g. French and U.S. production statistics1141). All have been cited in-line for verification. These sources collectively paint a comprehensive, factual picture of what a foie gras duck’s life is like under current standard practices. 1 9 56 57 63 64 70 71 89 91 99 111 Unseen Suffering: What Happens Inside the Foie Gras Industry https://thehumaneleague.org/article/foie-gras 2 5 7 8 10 11 12 21 23 24 25 26 32 33 36 37 38 39 42 46 47 48 49 50 51 53 54 55 61 69 73 75 76 90 92 93 94 95 96 97 100 101 102 103 104 105 106 107 108 114 Foie gras - Wikipedia https://en.wikipedia.org/wiki/Foie_gras 3 17 18 27 30 31 66 67 72 74 78 85 86 109 112 Farm Confessional: How I Learned to Stop Worrying and Love the Foie - Modern Farmer https://modernfarmer.com/2016/03/farm-confessional-foie-gras/ 4 98 FRCAW | Agriculture: the duck industry finds solutions to stop crushing female ducklings https://www.cnr-bea.fr/en/2021/12/15/broyage-canetons-femelles/ 6 13 14 15 16 19 29 34 35 45 58 59 60 79 80 81 83 84 88 113 The Physiology of Foie: Why Foie Gras is Not Unethical - Bella Bella Gourmet https://bellabellagourmet.com/blogs/news/the-physiology-of-foie-why-foie-gras-is-not-unethical?srsltid=AfmBOoo7UehwWzQZHj4oD4T_9lAEQKj59o4RsI-HQE19ITwssNrubfg0 20 52 62 65 68 110 The welfare of ducks during foie gras production | Animal Welfare | Cambridge Core https://www.cambridge.org/core/journals/animal-welfare/article/abs/welfare-of-ducks-during-foie-gras-production/084F38628B497EAFD274B611BD1237D3 22 Backwater Foie Gras, Farmstead, and Workshop https://backwaterfoiegras.com/farmingprocess 28 40 41 43 44 77 82 87 Hudson Valley Foie Gras | Cage Free Duck Foie Gras https://hudsonvalleyfoiegras.com/pages/why-cage-free
