Here's three pictures of her. She's a Dutch Bantum. The second one is a picture of her tail which doesn't really look right to me. My other hens' tail feathers all look fine and aren't splitting in half.
A lot of my chicken's tail feathers are breaking in half and falling out. I heard the mice could be causing it, but she lives inside in a small coop. He rest of the tail feathers look strange. I'm worried that all of them will either fall out or break and not grow back.
