Chickens

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. Chickens were a common fixture Greek life. 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]

Suffering and Violence
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]
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.[8] 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.[9]
Laying hens are bred to lay large eggs which they have not evolved for, stressing their reproductive system, and causing such problems as osteoporosis, bone breakage, and uterus prolapse.[10]
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.[11]
Crowding and Confinement
Debeaking
Debeaking is painful, causes lasting suffering, impairs feeding, eliminates exploratory pecking, and contributes to lice from impaired preening.[12]
