Last night I got home later than expected and didn't lock up the birds. When I went out to check/lock them I found one of my birds had been badly injured by what im sure was a raccoon. I found her relatively soon after, so we tried to bring her in and clean her up, she is now staying in the bath tub. It grabbed her wing and basically pulled all the skin off the top of her wing. It goes down deep, and she has little to no mobility right now. The rest of her body was ok. We disinfected it and tried to loosely wrap it in place so it would still get air in the wound. Anyone had experience with regrowing large amounts of tissue on chickens. We haven't seen a vet yet, we will probably have to bring her in. Just want to know if there's any hope in saving the wing. Picture below.
