Can anyone tell me why my Brahma has a bare bottom? Actually I have two (out of four) that look like this. Originally I thought it was from one of my barred rocks who I had witness pulling feathers off the others so I re-homed her. That was two months ago. Neither hen has grown any feathers back on their rumps. They both act fine and continue to lay but I can not figure out why this is happening. I only have 4 hens (3 white Brahma and 1 barred rock) so I’m pretty sure it’s not from over crowding. Does anyone have any ideas what is going on with these girls?
