I have a Black Austrolorp hen who appears to be going through a little molt. She has lost some patches of feathers on her head, and has pin feathers sticking out. A few months ago she "went broody" and pulled out a bunch of her breast feathers, which still haven't grown back. I noticed that the skin on this bare area is very flaky- like bad dandruff or "cradle cap." Is this normal, connected with the molting, or a sign of illness? She has not been laying well lately, but appears otherwise healthy. Thanks.
