Has anyone had any luck stopping the feather picking? I put in a Flock Block which I think they peck at a little but I think I'm going to have to go to pinless peepers on the one hen, let the others heal, and hopefully once they start free ranging again, the habit will be broken. I didn't get the pine tar cuz it had a big "Toxic, Fatal if swallowed" lable on it so I wasn't sure if it was the right stuff. I can see that the Rooster Booster hurts when I apply it on the worst victim's back so I will try an apron on her as well.
