How do chickens react to intensive farming?
If they grow up confined, they never know the difference and seem perfectly happy. They eat well, drink fine and and produce eggs and meat. If you take some of those pen raised chickens and turn them out, they panic and try to hide or find dark corners. I suppose it would be a bit like taking an kid raised in an apartment in LA and dropping him in the middle of a Western Kansas cornfield. Now if they’re raised loose, they don’t like penned. But they will adjust in a week or so. The instinct to survive seems to keep animals from pinning away with depression like humans do over changes they don’t like.
