I got home today and went out to check on the leghorn hens and found that the alpha hen has blood dripping off her comb. I only have 2 adult leghorns and the other one isn't the leader and I've never seen either of them fight since I've had them. They free range but I can't see anything attacking them and leaving them alive or just aiming for the comb. The temp has been around 40's to upper 50's. I read that cleaning the comb and spraying some Blue Cote on it will help her not getting pecked on, even though I don't see the other adult pecking nor the seven 6 week olds doing anything to her. Anyone have any clue why her comb would be bleeding.
