My chickens have been picking on each other for a good month now. At first I thought it was because I had two roosters and only 13-14 hens. After a hawk killed a rooster, now I have a rooster and twelve hens. The ratio is right, but the problem continues. I've applied Blue-Kote to the wounds, and pine tar over that every few days. Still got the problem, and it's getting worse. I've had to keep them in the coop and a 200 square foot inner run until I can cover the rest of the run because of my hawk problem. The egg shells are still very hard and high quality. I'm free-feeding Feather Fixer and ground-up eggshells to help with this. Out of 12 hens, 10 have been picked, and 3 have backs that are mostly bare. The pine tar doesn't seem to discourage them at all. l read a response on this forum from someone who actually duct-taped the bird's backs. I'm getting ready to go out to the coop some night with a flashlight and a roll of Gorilla tape! Anybody know any other solutions? Are they just bored at this point, or is there another problem? What health risks come with this intense picking?
