A couple of days ago, my neighbor's dogs attacked my chickens. Two are dead, one has several puncture wounds on her back. However I made the mistake of allowing the only chicken that was untouched to be I the same pen as her and now my injured chicken has a large hole in her back. She seems to be okay in that she still eats fine and can pass stool. She doesn't move around much though but when she does she can stand and walk without problems although she might have a broken wing as she doesn't move one of them. I'm just not sure if I should put her down because of the large hole in her back. It's about 1x 0.5" in size and probably an inch deep to the point where I believe I can see internal organs.
