Bottom sores ??

[MotherHen23]

I checked on blu’s bottom because I had noticed some redness. I knew she was growing new feathers but she has a sore or scab? I cleaned it and treated it with Mycrocyn AH. Should I be doing something else? Does anyone know what this is from? Thank you.

My guess is pecking since she has a couple of broken off feathers. Make sure they have enough room, and no one is bullying her.
