My young hen, Gamma, was just mauled by a dog. There doesn't seem to be any injuries other than a small nip on the back of her leg and many missing feathers, but I'm not sure if she has any internal injuries. She was panting earlier, but she ate and drank and seems to be fine. Are there any symptoms for internal injuries, like a punctured lung? Please help, these are my first chickens and Gamma means a lot to me.
