I was at the farm and feed store today, and there was a wounded hen there. She is a Rhode Island Red and the guy who worked there said she had been attacked by another hen and a rooster at her previous home. She was at the farm store for a week and a half. They gave her to me so that I could offer something nicer for her. Here's where the help is needed: she has a quarter sized spot on the back of her head with her skull fully exposed. It's horrible looking. I feel so bad for her. She is currently next to the other hens I have but in her own section of the coop. It is spacious and she started eating the goodies I gave her right away. Any ideas of what else I can do? Should I leave her in her own area for a couple weeks? How fast will she heal? Any ointment to help her heal? Pain meds? Exposed skull must be painful?!?! Any ideas will help, thanks all!
