My hen has a very bad gash on her back under her wing. Looks like the tom's toenails ripped the skin open. They were 1 yr old in March so this is their first breeding season. The tom still hasn't quite figured it out- he stomps her until she can't stand it and gets away from him. I coated the wound with Neosporin and will begin Duramycin in her water tomorrow. Anything else I should do -or do differently ? Thanks for any advice.
