Our Buff Orp picks on our 'Lorp and EE mercilessly. We took Buffy out of the flock and have had her in isolation in the basement since Friday last week. I took her out to the coop today and she went after the 'Lorp and EE. They ducked and squatted for her, she pulled their head feathers. She went after our RIR (who is head hen) and tried to attack her, but got a bloodied comb. I took Buffy back in the house because of the blood. I don't want her hurt. I just want the other two girls to stand up for themselves. I worry that our Australorp and EE are so timid that they will never defend themselves. I do have some pinless peepers. I was going to use them as a last resort. It looks like maybe it's the last resort, or should I keep her away from the other hens for longer? She's a pretty tough character, sweet as pie to humans, but a little terror to the shy girls. Any help or ideas would be appreciated!
