Good Morning. I live in Texas and my dog got ahold of my coop we lost 2 chickens and one is really injured. She made it over night and drinks and eats. I checked her out and under her wing you can see her skin must of torn because I can see her spine. I can not kill her what can I do to help her? I have seperated her in a dog cage but kept her in the coop. Any advice is great!
