In December I discovered blood in three nesting boxes and behind the feeder, which means someone squeezed behind it. I thought it was my hen Lucy since she had a few missing feathers. She has progressively lost more. There’s patches of missing feathers on her head, under both wings, and above her wings! I know she’s not molting because where the missing feathers are, there’s no visible quills. It looks like red scabs at this point. I am really starting to worry about her so if anyone can help, please tell me how I should fix this. This is Lucy. I took this on the third of March!
