I have a hen that I noticed has blood on the side of her comb. It wasn't gushing or anything, but enough to cover that side and to smear blood where it touches, and when she shook her head dots of blood get on the wall of the coop. I'm not sure where the wound is. When I first examined her, it looked like two tips had small flaps of broken skin on it. I'm thinking that's where the blood came from. As I am writing this, I went back out to look for exactly where the wound was, and the blood was all dry! She was bleed for 3-4 hours, and the last time I checked on her (20-30 minutes ago) it was still wet, and now...dry!... I read that chickens will mercilessly peck at blood and turn cannibalistic. Could chickens peck at the now dry blood and break it open again? I would wash the blood off, but it is toooooooo cold for that. She, along with 6 other chickens, are roosting now, so would they still peck? My other main concern is frostbite if the bleeding starts again. It is 12 degrees F here, and is expected to get to 2 degrees as the night goes on! Could a chicken get frostbite from wet blood on a bleeding comb? Thanks a bunch!
