Bald spot?? Over mating or mites?

[Keziah]

Hi everyone! So I noticed that my favorite hen (Muffin) had a patch of her fluff showing, so I went to see what was up and found her back almost completely feather-less. It almost looked like a broody hens belly, but on her back. She also had scabs and super super dry looking skin on her back in the same spot. It looked to me like another chicken pooped on her and she tried to get it off by pulling out her feather or something. I gave her a bath and soaked her Feathers while trying to get some of the gunk/poop looking stuff out, and that is where I am now. I have her sitting on my lap in a towel Burito and her cute wet feathered head is looking at this screen for answers! What do I do next? What is this? Any similar experiences?

Do you have a rooster? It looks like it might be from breeding. Maybe using coconut oil moisturize the dry skin.

How old is she? Do you have a rooster or cockerel? Overmating can cause bare spots, and also feather picking.

Yes, I have 2 roosters, they are the same age as her (about 6.5 months)
