Last night I noticed bright red blood on some surfaces in the barn. Everyone was roosting and no one looked bloody. The cockerals have been sparring so I assumed it was that. This morning one of my sumatra girls was roosting on a metal gate all alone. This wasn't like her, so I picked her up and checked her over. She's missing her toenail and it's a bit bloody, not dripping. I cuddled her and gave her a handful of scratch and put her near the heat lamp. I can not for the life of me, figure out how that could have happened. Her foot looks fine exept for the missing nail. Should I give her anything?
