Iʻm currently stuck and Iʻm not sure what to do next. Any helpful advice works.. I have two Rhode Island Red hens (siblings), two White Leghorns, and three Barred Rock (the Leghorns and the Barred I got them together, probably siblings). Lately the two RIR sisters have been bullies... One of em, the biggest out of the two, her name is Big Red. Sheʻs the bully hen. Her sister, Little Red, is the mean hen. Big Red will pick on her sister a ton but they are inseparable. I gotta keep them together or one or the other will freak out, cluck and call for the other until they're together. Big Red is such a bully hen that she has begun to pick at her sisters back feathers, and eats them. She has even started to disturb her sister from egg laying and Iʻve caught her eating Little Redʻs eggs once or twice. But Big Red is soon mean! Little Red on the other hand, will not fight back her sister. But to the other hens, she will peck and chase them away. Big Red will also do the same, but with more consistency. The other hens will do anything they can to stay away from them or get out of their way, but sometimes running away from them triggers Big Red to chase them. I want them to all get along but Iʻm not sure what else to do. -I have pinless peepers on both hens, but it only worked a few days until things went back to normal; being bully hens. Iʻve separated the RIRʻs from the rest of the flock, but this has only made things more worse for Little Red because sheʻs taken the beating. Since then, she's bald on her lower back. Its regrowing, thankfully, but Big Red has still been picking so much it grows sparsely. -I have tried putting the RIRʻs in a pen within the original pen, but the RIR still bully each other.... -Right now, I have Big Red in the pen within the original pen by herself, and Iʻve left Little Red outside the pen entirely to roam freely. I hope to have her feathers to regrow and eventually learn that she can be without Big Red. Little Red can still see Big Red but she's outside the pen and canʻt get in. She has all the freedom in the world, but she chooses to stick around the pen. Iʻm hoping this method works, but Iʻm doubtful. I will eventually let Big Red out on probation and if she goes back to doing what she does, then back into the little pen she goes. If anything... I was considering culling the RIR or giving them away to a friend.
