we recently got chickens and when we got home last night one was missing. A hawk had tried to attack one of them the other day so I thought that the missing hen was killed because She never ended up coming back and wasn’t around this morning either. I opted to leave the other chickens locked up today because I didn’t want to lose another, but I just came home from work now today she was sitting outside the coop waiting for me. She appears to have a really deep wound in her back that to me almost looks like a bone has been broken and if I put my hand over the area every time she l exhales I can feel warm air coming out and actually hear a puff of air. If anyone has a suggestion of what to do for her I’m all ears. She’s currently eating and drinking fine and the area isn’t bleeding.
