Eight days ago a raccoon got a hold of 10 of our chickens. Four were dead and Five were dragged off never to be seen again. Five survived. One of my chickens had an injured wing but she didn't seem bothered by it. On further inspection her wing is missing and the bone is sticking straight out. She still acts like nothing is wrong. It looks horrible! I'm concerned that it could get infected and make the rest of my chickens sick. I'm brand new at being a chicken lady. I'm about as city as they come! What should I do about this poor chicken? Please advise!
