My six month old puppy got one of the hens who escaped the coop. He plucked out lot of the feathers on her back. Along with some flesh. It’s been a week, and she was isolated in a dog crate inside because it was snowing out. During that time, she actually laid an egg. Because her back was scabbed over I put her back in the coop, and the other chickens appeared to not mess with her but when I checked later in the day, her entire back was bloody. One of the chickens was pecking at her. I put her back in the dog crate inside last night and now it looks like this. Any suggestions? So far I’ve been rinsing it with saline and putting triple antibacterial ointment on it.
