I have noticed blood drops and some healed wounds on my smallest hen. Today I witnessed the rooster (instead of grabbing the neck feathers like he does the bigger hens) he bit her comb and ripped it about .5 inch or more. I was able to get her and I set her up in her own private, spacious, chicken suite. she was bleeding so much her whole head is red, so I dabbed it with warm water. What else should I do?
