I have a cuckoo marans pullet named Pepper. She is disabled and can't walk, so I have her set up in a cardboard box that I can move around. She has been disabled for 3 months. 2 days ago I found her comb bloody. I figured that she had probably rubbed her head against the box too much, or another chicken pecked her. My BO seemed to like to peck at her healing comb. Today, I looked at her and saw that the skin by the top of her comb is BLUE "( What's happening? Did my BO peck something that made her turn blue? HELP!!!! How do I fix this?
