All ten of my hens are about a year and a half old. During molting about three weeks ago, the chickens began picking on Sugar. I caught them pecking her and pulling her feathers out and eating them. In a days time they pecked and pulled almost all of her feathers out. I put a dog carrier in the coop and kept her separate from the other girls for the last several weeks. Now she has a good start to the new feathers and I want to let her run with the rest of the flock. All the chickens, even the most subordinate ones, are pecking at her and are very aggressive. I have never raised chickens before and I am afraid they will hurt her badly if I just leave her in the run with the other chickens. They have a good size run and coop. I keep them inside during the day while I am at work. I put the girls in the run and close the door to the coop, and keep Sugar in the coop away from everyone else. I let them run the yard during the day on Saturday and Sunday. While in the yard Sugar stays away from the rest of the girls and does okay. Should I just let her out into the run with the rest of the girls, or is she a marked hen in the others eyes, and will they hurt/kill her if I leave her with them and am not there to protect her. Don' know what to do. I need advice please. Thank you.
