“Meat birds spend their lives in barren sheds—or “broiler houses”—that may hold 50,000 birds and be so crowded it is difficult to see the floor. In these conditions, they are unable to carry out any of their natural behaviors, such as foraging and roosting, and the birds develop psychotic, stress-induced behaviors, such as feather pecking and cannibalism. Often, in order to prevent the birds from pecking each other to death, a hot blade is used to cut off the front part of their beaks, without anesthesia, at birth. This procedure, known as debeaking, can lead to infection, the growth of neurological tumors, or death if the bird doesn't have enough of a beak left to use for drinking or eating.”
