so about 2 weeks ago my chicks went outside to be with my full grown chickens. So a couple of days ago I noticed one of the chicks has a big hole in its back. I'm assuming it got pecked by a big chicken. You can see inside the hole. It's very dry and gross. The chick also walks funny. Will it survive or should I put it down? He still eats and drinks and walks, he just limps. I included a photo.
