my two month old chick was injured by my son's cat. He said he heard noise and when he went to check the cat was on top of the chick. My question is how do I tell if her leg is broken or out of socket. There is no blood or obvious punctures , but she can not put weight on the leg. She holdsit still it is cold and she is in pain. Evry now and then she will start panting. Can someone suggest what I should do or how to tell what is wrong?
