Oh boy, I've got trouble. After about 2 weeks apart but visual to each other, I picked last night to introduce 2 young chickens (14 weeks) to by 2 existing hen (1.5 yrs). Under the cover of darkness, I put the new birds onto the roost in the coop with the door open to minimize any "encounters". I checked them at 6AM to discover 3 of them out roaming in the run and the 4 standing very still at the chicken wire fence, so still I was sure she was dead on her feet. She's not but what a mess. Her head/comb pretty much looks like it has been scalped. I can see her skull. It's bloody but not bleeding. She can walk but is a bit unsteady. I DO NOT want to prolong her suffering if this is beyond help. I just don't know what to do - please, any advise!!! PS I have reseperated the chickens!
