A couple of week s one of our mature hens came out of the coop limping. So I went and caught her but I can not find any swelling or cuts of any kind. She walks almost like something is out of place. We have contained her on mabe it might be broken. She didn't improve. We got her and other of the same breed from a store(eek). One of those hen hatched out a chick and now the chick is limping as well. Could this be a genetic thing? If not, how do I fix it? Help!
