I wholeheartedly agree. Mine are pastured (when they free range, they get eaten by predators) and they mock-fight and waddle around and try to catch bugs. Then they have to stop and rest, but they still move and are chickens. If I couldn't let them out to play every day, I wouldn't raise them. I don't really enjoy them and their huge amounts of poo, but for us part of the point is that our meat had a chance to be a chicken while it was still alive.I guess to me, the point of raising my own meat is to have it raised better than Foster Farms does. An 8 week old meatie, just sitting still, takes up at least a square foot right there.
My Cornish cross have been free ranged and you'd be surprised how much they'll move around, given the chance. Granted, not as much as my active layers, but how much can you expect them to move when each bird only has that much space? Your birds physically CAN'T move around.
