Any thoughts/suggestions would be appreciated. My 3 week old chick was attacked by another adult hen this afternoon. He/she has a wound under her wing and possibly some air under the skin at the wound site. I cleaned her up and put her into a cage to rest, but I'm concerned that she is having difficulty breathing. She will occasionally pant and stretch her neck out in front of her. She also will not put much weight on the leg on the same side as the wound. There does not appear to be a fracture in the leg. Please help!!
