I have 3 roosters and about 20 hens. I have 1 barred rock hen and I believe she is head chicken. Anyway, her back between her feathers is down to skin and bleeding. Plus her butt is red and raw. I think the roosters are using and abusing her too often. I have removed her from the flock and put her in a nice big crate with food and water and I am thinking of adding blu kote to help her heal. What can I do to keep her safe after I introduce her back to the flock? Do you think once she is missing for a while they will leave her alone when she comes back? None of my other hens have any issues. Thanks for any advice you can lend.
