We got a new rooster for our 3 girls since they free range, one of them is getting severely picked on and her head is completely raw and now her neck feathers are being plucked out! She refuses to go back in the coop so we’re trying as best we can to keep her in a kennel in the house at night to stay at warm and feed her! Any thoughts on to why this might be happening?? They were ok for the first week or so just seems like they’ve abandoned her
