My moth old chickens are eating feathers. I have increased their protein level but still they eat feathers. I give them timothy hay and cracked corn to keep them munching in there pen along with their feed. I tried rooster booster anti pick rubb but they still pick at each other from time to time. They keep eating wild bird feathers too. They are not old big enough to be let out, they can slip through the fence and I'm still trying to find out about them and the peafowl. Any suggestions out their???????
