Would a rooster do this? Or at least start it and then the others chimed in? This is the first injury I've had to deal with since owning chickens. We have two Lavender Orpington roosters that have just come of age and I have noticed one of them grabbing girls by the head. The meat is torn all the way to bone/skull. I have cleaned it up and put every antibiotic I have on it and am giving her tetracycline via water. She is eating meal worms from her water.
