I am having a bit of trouble with my flock integration. I have 4 one year old hens (1 BR & 3 golden comets) and got 3 five week old RIR's in July. They were separated in the the main coop for 8 weeks and started free ranging and open in the coop at 13 weeks. I know that was fairly young but they were getting too big for the separate area and we were leaving for vacation. Now, at 16 weeks, they sleep together in the roost but probably because the 16 week olds are scared and run up there. They are still afraid of the big girls and will run off even one hen even looks at them..I have one hen that is particularly threatening to them. She chases them, gives random pecks, keeps them from food, etc., a troublemaker overall. Should I re-home her? Will that help the situation? Should I just wait it oout? Will this ever work out? They are all just about the same size now and I have to be able to keep them in the coop soon since winter in Vermont in cold and snowy. HELP!!!
