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]
Early interest in these birds centered around cockfighting, but later the bird became domesticated for eggs and meat. Chickens were used widely in Southeast Asia, India, Tibet, and the islands of the Pacific. By the sixth century B.C. Egyptians were using chickens for religious sacrifices and cockfighting, and by the third century they were being used for their meat and eggs.[2]
Chickens were a common fixture in ancient Greece. After being shown a chicken, Plato defined humans in terms of the chickens as "bipeds without feathers". Their exploitation in the West spread from Greece to Rome and then on to Europe. [2]

Mass Slaughter 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.[3])
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.[4]
Overcrowding and Confinement
The vast majority of layers still live their lives in battery cages, unable to preen or spread their wings. In 2009, 95% of all egg production is from hens kept in cages.[8]
Cage-free chickens are frequently subjected to overcrowding. According to Dan Flynn, who has more than 15 years experience in food safety, writing for Food Safety News, says that "overcrowding and a lack of access to the outdoors are frequently cited at operations billed as cage-free…"[9] As you can see by the abundance of images and videos available with a quick Google. the crowding is severe, restricting or eliminating the chickens' ability to express their natural behaviors of nesting, perching, dust-bathing, and pecking. Undercover investigations at human certified farms show that the standards are not enforced and abuses still occur. One such investigation at Pitman Family Farms revealed that even the lowest level stipulation of "no cages no crowding", which is supposed to be adhered to for all animal foods sold at Whole Foods, is not even close to being enforced. According to one investigator of a Whole Foods certified chicken house they "replaced cages of wire with cages of flesh." The video shows:
- Congestion so bad that in some areas the hens were piled on top of each other.
- In other cases, birds received no more than a square foot of space.
- Chickens that had lost all or most of their feathers from the crowded filthy conditions. You could see the rashes, inflammation.
- Chickens bumping into each other and squawking in agitation.
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.

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.[11] 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.[12]
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.[13]
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.[14]
Debeaking
Debeaking is painful, causes lasting suffering, impairs feeding, eliminates exploratory pecking, and contributes to lice from impaired preening.[15]
