I'm trying to solve a plucking problem of four against one. My SLW is getting her tail feathers plucked out by four others. There was blood. I took her inside our porch where at least she wouldn't keep getting plucked. I was told to try Blue-Kote. Can you buy that at Farm and Fleet? Also, once the stuff has been sprayed on, then what? When can I send my chicken back to the coop? Will she still get plucked?
