Some chickens are raised that way., some are allowed to play in groups in yards. Ultimately it is a question of economics. I don't find much difference in my cooking using chicken breasts that sell regularly for $1.79 a lb vs. those that sell for $2.99 a lb, except that I save a boodle. Likewise with regular eggs vs, those "organic" variety. Nobody that eats my food seems to be able to tell the difference none either. Now they can tell right away when I am using grouse or chukar or pheasant.
