I think one of her sisters accidentally pecked at her comb, because it's bleeding. Should I put a bandage over it, or let it scab and clean it up? While examining her cut, I noticed she's losing feathers around her neck... Is that a molt? Or something else. Here's some pictures from both sides of the feather loss and the comb. All of my chickens are 13 months old, and she's the only one losing feathers.
