I have 4 RIR that have been together since the summer & started laying in December. I get 2-3 eggs a day. I started noticing some bald patches on one chicken, then a second, then a third. I separated the only one without feathers missing (Big Mama). Then, I noticed the pecking from one of the remaining three! So I also removed her (Chickaletta). The two left in the coop have bloody tails & I want them to heal. But, Big Mama started attacking Chickaletta in the cage. So, I had to put her back in the coop this morning. Unfortunately, Chickaletta started pecking the other two almost immediately. Big Mama remains isolated, but I fear the others are going to get pecked on pretty bad & not have a chance to heal. Is this normal? What else can I do. I don't want to get rid of any of them. I'm going to get more water & feeding options. Any recommendations for toys? Change the feed? Thanks
