I just noticed one of my hens is injured. I would have never seen it if she didn't escape her run just now. She seems unbothered by it but im guessing a hawk tried to snatch her. She's missing chunks of flesh on both sides of her back. The skin in the area is hard/dead. I have no idea what to do, I'm not sure if putting antibiotic ointment on the wound would be a good idea since it's a deep injury.
