I have a RIR that is about 10 months old. She has always been a bit of a bully with my group of 6 younger chickens. We got them when she was about 5 months old, and she just doesn't tolerate them very well. She will deliberately find ways to push them around. If I put out scratch, which I do in small piles rather than scattering it, because it gives them space between each other so there is no fighting, each chicken has a small pile to themselves, she insists on going from pile to pile and pecks the younger chickens away when she gets to their pile. They have come to learn she is mean to them, and they give her a wide berth, which is fine, except for the new problem I have encountered. She doesn't let them go in the coop to lay their eggs. At night, when they go to roost, she makes sure the younger chickens do not come to the end of the roost that she is on, but will allow the older chickens to be there. She is not the top chicken, and I do understand pecking order and it's purpose. I don't interfere as long as it doesn't get out of hand. If it's a quick peck, I let it be. Now, the younger chickens have started laying eggs. So far two are laying, but, two more are really ready and will start any time now. The first one to lay was our Austrolorp. She was laying in our cat's igloo outside, but, when I found where she was laying them, I made it impossible for her to get there or anywhere else that she could hide her eggs. I kept showing her the nesting boxes in the coop, and offered her a large low basket as an alternative, which she liked, but, the RIR seemed to know the Aus was trying to lay an egg and she kept coming into the coop and trying to get to the Aus. I knew she wasn't interested in being friendly, and didn't want her to peck this poor little chicken who was already stressing that the RIR was even in the same space as she was, so I chased her out of the coop. Still, the Aus was determined not to lay her egg in the coop, and kept wandering the yard looking for another place. None of the younger chickens will go in the coop or run when the RIR is in there. She chases them out. The Aus kept running up to me like she wanted me to help her. I just took her back in the coop and put her in the basket or a nesting box. It was so sad how stressed she was. I've seen chickens stress when they are laying those first eggs, but, this was so much worse. Finally, with no other choice, the Aus hid behind the nesting boxes and laid her egg on the floor of the coop. Two days later the Aus was stressing again and the RIR was chasing her out of the run. I had to put the Aus in the coop, and close the door so the RIR couldn't get inside. After I knew the Aus was settled in and laying, I opened the door and the RIR went on in. She didn't bother the Aus, maybe she couldn't find her, I don't know. But, then one of the EE youngers started looking for a place to lay, and sure enough, the RIR chased her away from the run. I don't want to give away the RIR if this is solvable, but, I guess I'm hoping to hear what others think about this and what you would do. I work when they are laying, so, I can't always be there to run interference and I can't just put her in a dog crate 24/7 in this cold weather with no friends to help keep her warm. Help.
