My Black Star started molting a week ago. The other day I noticed her butt was bare and part of it somewhat swollen and very raw. I've posted a picture. I've rinsed her with saline and put mess in her water for worms (but I don't see any in her droppings which are very loose). Any advice? She seems thirsty and she eats pretty normally. She can't stand to be picked up I imagine due to her almost complete loss of feathers. Any advice would be greatly appreciated. Thanks.
