I would have taken out the bully instead of the victim. I have a Yokohama cockerel that was a bully. He is way to small to eat, but I moved him into the Guinea Gulag. He is no longer a bully. He is waiting for the Nice Asian lady to make a trip out with her plastic lined trunk to haul him away. Once the instigated was gone the pen became calm again.
They drew blood so it was a loosing battle after that. With a tractor full of CXs it's hard to say if there was just one bully.
