I found an injured chicken. She has a puncture wound under her wing. I've researched and I think she's a Polish. She is eating and drinking well. Seems to be a decent weight. Doesn't seem to be in pain. Her wing droops and she can't use it. I've cleaned wound with warm salt water and put Neosporin on it. It is draining some blood from it still. Is there anything else I can do for her? Also going to bathroom well and it looks normal.
