Read the following paragraph and think about what the author means by the underlined sentences in the paragraph? You have also made all types of wild birds into chickens-creatures with wings so impaired that they cannot fly. There are farms where you breed chickens for breast meat. Those birds are kept in low, repressive cages, forced to be hunched over all the time, which makes the breast muscles very big. One loud noise and the chickens go mad, killing themselves by flying against the walls of their cages. Having to spend all their lives stooped over makes an unnatural, crazy, no-good bird. It also makes unnatural, detached, no-good human beings.
