" Chickens are the creatures of the earth who no longer live on the land. In the industrialized world, billions of chickens are locked inside factory-farm buildings, and billions more are similarly confined in Africa, Asia, India, China, and other parts of the word where poultry factory farming is rapidly supplanting traditional small farming. If there is such a thing as "earthrights," the right of a creature to experience directly the earth from which it was derived and on which its happiness in life chiefly depends, then chickens have been stripped of theirs. They have not changed; however, the world in which they live has been disrupted for human convenience against their will. "
