My apology. I obviously missed that part at the bottom where you mentioned your 30 s.f. coop and 90 s.f. run. My "again" was in reference to previous post before mine (by MMF) My suggestion to separate them from each other is b/c they are bonded to each other, and b/c they are top dogs, they will enable each other to continue the cruelty when you put them back with the rest of the flock. An other thought might be to separate the flock into 2 groups with 1 RIR in each group. Hard telling if that would accomplish anything. Do you have an option of dividing your coop and run, keeping fencing between the RIR and PBR? It's a tough situation for you to deal with, especially since they are pets. It would be so nice if they could just play nicely, wouldn't it???
