I know this subject has been already discussed but I need some help. I recently lost 4 of my hens (neighbors dog) I now have two hens and one rooster. He has picked one of my surviving hens as his favorite.....she is bald on her back and yes I do have a saddle on her now but where her grabs her head is also bald. She looks terrible and I feel so bad for her. What should I put on her head? They are free range....I can keep her in the coop but it is not movable. I put the rooster up to give her a break. What if anything should I put on her (medicine?) Thanks for the help!
