This is a draft. It will remain in the Staged namespace until it is completed.
This article provides information about chickens that should prove useful to those exploring the rationale for veganism, as well as to those advocating for animal rights. After providing a bit of general information on chickens, it summarizes a number of injustices and ways chickens suffer.
Then, lest anyone think the suffering is substantially mitigated by purchasing products with a humane label or certification, we show why conditions for chickens sold with various certifications and labels were only marginally improved if they were improved at all.
After that, we discuss the sentience and cognition of chickens, exploring their rich emotional and cognitive lives, as well as their ability to suffer. Finally, we point out the human health risks associated with eating chicken meat and eggs.
General Information
It's commonly thought that the domesticated chickens used for meat and eggs are primarily descended from the Red Jungle Fowl of Southeast Asia. More recent research paints a more complex picture—birds from India, Cambodia, Ceylon, and other areas may also be involved in the lineage.[1]
Chickens were used widely in Southeast Asia, India, Tibet[2],and were a common fixture in ancient Greece. Their exploitation in the West spread from Greece to Rome and then on to Europe. [2]
Globally, over 76 billion chickens are slaughtered annually for meat and another 11 billion laying hens are slaughtered when their female reproductive systems are used up and they are no longer profitable.[3] In the United States, the figures are 9 billion and 375 million[3]. Far more chickens are slaughered than any other farmed animal.[3]
Sentience and Cognition
Injustices
The injustices and abuses to chickens discussed below are either standard procedure or not unusual. Each of the abuses discussed below will apply to many, if not most, chicken products—even those with a humane label or certification. The pressures of production require animals to be mistreated in order to be profitable. To omit a significant number of these injustices would render the products unaffordable by all but the most affluent.
Loss of Life
Slaughter
The process of slaughter...
Mass Extermination of Male Hatchlings
Because laying hens are bred specifically to lay eggs, males hatched from the laying hen variety of chicken are not profitable—they don't yield sufficient meat and they can't lay eggs. And because they are not profitable, the males are ground alive in a macerator, gassed, or suffocated, shortly after they are hatched. This industry refers to this practice as chick culling. (Weak and struggling females are also discarded in this manner.[4])
Hatchlings are about 50% male and 50% female. So statistically speaking, every laying hen has a brother who has been violently slaughtered. This is true even for backyard chickens, as the female hatchlings are sold not only to commercial producers, but individuals keeping backyard chickens.
In the United States, over 375 million male chicks are slaughtered via culling. Worldwide, it's in the billions.[5]
Overcrowding and Confinement
Suppression of Natural Behaviors
Filth and Stench
Filth, stench, and feces were everywhere. Many of the birds were covered in feces and so weak that they could not clean themselves. Have to live their entire life in suffocating stench of feathers, dander, urine, and species. Some were stuck in manure so deep it could be described as a manure pit. They were almost buried in their own feces. Some were splayed out on filthy concrete floors barely able to breathe.
Sickness and disease were common. Some we so sick you could hear them struggling to breathe. Some hens didn't have the strength to stand on their own two legs. Some barely able to move or respond to anything around them. Birds were found dead and dying. Chickens that had lost half their body weight.
Investigators were overwhelmed by the constant cries of distress.

Other conditions inside the warehouses add to the misery of the confined birds. To mention only one, for brevity's sake: the ammonia-laden air in the chicken houses is so noxious that the birds commonly suffer respiratory disorders, severe flesh and eye burns, and even blindness.[10]
Spread of Disease
Battery Cages
Despite failed and weak legislation and the federal and state levels[11], and despite the trend for producers and grocers to promise to go cage-free[12], as of 2014 over 95% of eggs involved battery cages[13]. There is little evidence that the situation has materially improved since.
Hens in battery cages spend their lives confined to a space less than the size of a standard sheet of paper,[14] preventing or hindering their ability to turn around, preen, spread their wings, or scratch for food.[15]
Dibilitating Selective Breeding
A laying hen produces more than 300 eggs a year, but the jungle fowl from which they are bred lay less than 10 eggs in a year. This causes both physical and physiological stress.[16] The large increase in the number of eggs laid is from a combination of selective breeding as well as the tendency of the hen to lay more when eggs are removed in order to follow her instinct to form a proper brood.[17]
Laying hens are also bred to lay large eggs for which they have not evolved, stressing their reproductive system, and causing such problems as osteoporosis, bone breakage, and uterus prolapse.[18]
The modern broiler chicken is unnaturally large and has been bred to grow at an unnaturally fast rate and have large-sized breasts. This selective breeding comes with serious welfare consequences, including leg disorders, skeletal, developmental and degenerative diseases, heart and lung problems, breathing difficulty, and premature death.[19]
Debeaking
Debeaking is painful, causes lasting suffering, impairs feeding, eliminates exploratory pecking, and contributes to lice from impaired preening.[20]
Rough Handling
When chickens raised for meat reach their desired slaughter weight, they are caught, created, transported, unloaded, and placed in holding pens until slaughter.
A review of videos of these activities shows squawking birds bring grabbed 4 at a time by their feet being roughly thrown or shoved into crowded crates, birds suffering dislocations and broken bones, wings and heads crushed in crates, feed withdrawal, birds dying from suffocation, heat and cold, and birds unable to stand from exhaustion. [21][22]
Research bears this out—a 2016 study in Poultry Science revealed that in addition to the physiological stress these procedures inflict, it is not unusual for a bird to experience dehydration, disease, injury, and pain, and even death. The injuries include wing and leg fractures, lesions, bleeding, bruising. [23]
Light Manipulation
Osteoporosis
Forced Molting
Mental Illness
Humane Labels and Certifications
Investigations by Consumer Reports, The Open Philanthropy Project, and numerous others reveal that these certifications and labels are largely meaningless, as shown below.
These investigations show that the standards are weak and unenforced, audits and inspections are rarely done, and if they are done and violations are found, which is infrequent, no one gets fined.
Cage-Free
Consumer Reports advises you to “ignore cage-free claims” for chickens.[24] "'Cage-free' does not mean the chickens had access to the outdoors." It only means the chickens were not confined to a cage.[25]
Cage-free chickens, like free-range chickens, may be confined not by a cage but by crowding so extreme that turning around and engaging in the natural behaviors of preening, nesting, foraging, dust bathing, and perching is difficult or impossible. Such extreme crowding in large metal warehouses is the norm.[26][27]
Free Range
The USDA standard for free-range requires only that chickens are given some access to the outdoors. There are no stipulations for the size or quality of the outdoor space, and there is no requirement that the chickens actually spend time outdoors.[28] Also, the claim does not have to be verified through inspections.[29]
So it's not surprising that investigations by Consumer Reports (and others) reveal that most chickens labeled free-range spend their lives confined inside a crowded chicken house. The free-range space itself may be nothing more than an enclosed concrete slab that the chickens never use. These individuals lack the room even to turn around, much less engage in their natural behaviors of preening, nesting, foraging, dust bathing, and perching.[29] This has led Consumer Reports to say that free range is one of the most potentially misleading labels because of the discrepancy between what it implies and what is required to make the claim."[29]
Only one percent of eggs are from free-range hens that have the option to go outdoors, but like the other 99 percent, even those hens have likely never actually been outdoors.[30]
Jonathan Foer, in his well-researched and fact-checked book[31] Eating Animals, sums it up well in saying that "the free-range label is bullshit" and "should provide no more peace of mind than 'all-natural,' 'fresh,' or 'magical.'"[32]
Whole Foods Market (GAP)
Whole Foods Market spearheaded development of the Global Animal Partnership (GAP) certification program and sells various products, including eggs and chicken meat, with GAP labels.
The Open Philanthropy Project criticized GAP for having weak enforcement and for providing only slight improvements over standard factory farming conditions.[33] For example, according to Consumer Reports, "standards for slaughter do not exist at any level for chickens and there is no limit on their rate of growth."[34]
Organic
Some have the perception that chickens with the organic label means they are humanely raised, but that is not the case. Organic farmers are free to treat their animals no better than non-organic farmers. This is because the USDA, which controls the organiclabel in the United States, ruled that the label does not allow "broadly prescriptive, stand-alone animal welfare regulations."[35]
Consumer Reports informs us that while there are organic standards relating to animals, they lack clarity and precision, letting producers with poor standards sell poultry and eggs.[36]
United Egg Producers Certified
Consumer Reports says that while the label is verified, "it is not meaningful as an animal welfare label because certain basic conditions, such as the freedom to move, are not required."[37]
American Humane Certified
According to Consumer Reports, "the requirements fall short in meeting consumer expectations for a 'humane' label in many ways."[39]
Animal Welfare Approved
This is the only certification that Consumer Reports says has strong standards, yet the standards still allow for mutilations[40]and other injustices. Also, products with this label are challenging to find. A search using their own product finder reveals that it's unlikely you will find any products with this label at a grocery store near you.[41]
Certified humane raised and handled
Consumer Reports says that "we do not rate Certified Humane as a highly meaningful label for animal welfare, because the standards do not have certain requirements that a majority of consumers expect from a 'humanely raised' label, such as access to the outdoors."[42]
Backyard chickens
Although backyard chickens are not associated with a certification or label like the others that we are covering here, they deserve a closer look. A considerable number of people regard the practice of keeping chickens in the backyard for food as innocuous.
Baby chicks often die in transport. A quick search will find numerous reports of chicks being shipped alive to backyard hobbyists and dying in transport—and reports of those that make it being greatly stressed.
Backyard chickens are the same varieties or similar varies as commercial chickens, and are subject to all of the abuses that result from culling and selective breeding, as discussed below.
Backyard hens are likely to be slaughtered when egg production wanes, preventing them from living out their natural lives. As one hobbyist euphemistically put it, "when the expenses outweigh the value, then changes have to be made."[43]
The slaughter of backyard chickens whether laying hens or broiler chickens, is usually done by slitting the throat and waiting for the convulsing chicken die its slow death. The slaughter is violent, cruel, and painful, just as with commercial operations.
