Ok so we have had all of our chickens together for almost a month. We intergraded the pullets and hens. Lately we have moved all the chickens into the chicken tractor and about half way through the day we will put the hens back in the coop so they can lay. We leave the pullets in there during the day and in thier coop at night. Today when I put a couple pullets in the coop one of my araucanas (Annalise) Chased after one of them and tore a mouthful of feathers from it and ate them. Boba (another araucana) came over and ate them too. Why are they doing this. It's the first time they ate the feathers as well. Is it a bad sign?
