black bloody comb/head

[ShannonSherman]

My buff orpington has a chunk of comb that is sort of hanging off and dark and bloody today and there seems to be some blood on her head too. She is acting different, not eating as much, slower, etc.
Do you think another animal did this to her or could it be frostbite?
thanks!

Sounds like an injury, probably from another chicken. Are you keeping them cooped up.
