For every egg-laying hen confined in a battery cage, there is a male chick who was killed at the hatchery. Because egg-laying chicken breeds have been genetically selected exclusively for maximum egg production, they don't grow fast or large enough to be raised profitably for meat. Therefore, male chicks of egg-laying breeds are of no economic value, and they are literally discarded on the day they hatch — usually by the cheapest, most convenient means available. Thrown into trash cans by the thousands, male chicks suffocate or are crushed under the weight of others.
Another common method of disposing of unwanted male chicks is grinding them up alive. This can result in unspeakable horrors, as described by one research scientist who observed that "even after twenty seconds, there were only partly damaged animals with whole skulls". In other words, fully conscious chicks were partially ground up and left to slowly and agonizingly die. Eyewitness accounts at commercial hatcheries indicate similar horrors of chicks being slowly dismembered by machinery blades en route to trash bins or manure spreaders.
http://www.factoryfarming.com/eggs.htmThe chicken’s misery begins at birth, when he or she is among thousands of chicks hatched in an industrial incubator. At this point, agribusiness doesn’t even call them “chickens.” Instead, these birds are identified by their food value: “broilers” are chickens bred for meat, and “layers” are hens destined to produce eggs. Workers in the egg industry quickly separate the male and female chicks, literally throwing out the males. Because “egg-type” male chickens can’t lay eggs and are too small for the broiler chicken industry, they are either gassed, tossed into a machine that grinds them up while fully conscious, or flung into garbage bags to eventually suffocate. U.S. hatcheries killed more than 272 million male chicks in 2002.
http://www.satyamag.com/mar05/hawthorne.htmlPerhaps the finest illustration of what factory farming does to chickens has been presented by artist/writer Sue Coe. After her visit to a hatchery with Lorri Bauston from Farm Sanctuary, the activist organization focused on rescuing farm animals, Coe wrote about what they found:
“Around the back is a large dumpster. Lorri and I climb up to look inside. She is looking for live baby chicks. The male baby chicks are discarded as soon as they are hatched. They have no use, no value, since they cannot lay eggs. And it would cost too much to euthanize them. So they are tossed into the dumpster alive. But it is too late for us to rescue any chicks—the sun is just too hot. On the top layer of corpses, flies are eating the chicks’ eyes. Lorri keeps digging under the corpses. There are layers upon layers, some chicks still half in the shells, having broken through with their beaks. I examine a chick, so perfect with its soft yellow down and tiny wings. The chicks are thrown in with other garbage: empty Coke cans, cigarette packs, computer printouts, samples of our throwaway society. Gene Bauston, cofounder of Farm Sanctuary, told me that sometimes the baby chicks are ground up alive and thrown on the fields as fertilizer. Walking along a plowed field, you can sometimes find a chick, still alive, with no legs or wings.”
