Looking for some advice on caring for my rooster's "favorite" hen. He's scratching her under her wing on one side pretty bad, about the size of the bottom of a coke can. Most of it is scabbed over but she has some fresh open cuts. I plan to isolate her until she heals, but is there a spray I can use to help? Peroxide? A way to prevent him from hurting her or my other hens? Is it just a normal part of mating? All of the birds are about 8 months old. He's a beautiful rooster but I'm considering getting rid of him if he continues to injury my hens. I have friends who will take and raise him. Thanks for the advice!
