Culling bullies is certainly a very efficient method of stopping aggression. It's a viable and reasonable option.
However, if any of the bullies are valued layers, I have discovered a very effective way of disciplining a bully, but it requires your presence among the flock from time to time to reinforce it.
I'll describe the technique with a story about one of my worst bully hens. Edith is a BO who came to the flock about three years ago as a rescue hen after her flock were all abandoned by their owner and then all but Edith were killed by a predator. Edith was successfully integrated into the flock and she quickly developed self confidence, perhaps too much.
She began to be a bully, chasing and terrorizing a few timid older hens, mostly at roosting time. I bought two fly swatters and hung them in handy places in coop and run. When Edith would start in with her bullying, I would grab a swatter and give her a smack on the butt. That stopped the bad behavior on the spot.
After just a few days of this, all I needed to do is grab the swatter and show it to Edith to interrupt her attempts to bully. Occasionally, Edith tries to sneak into a nest box to sleep. All I need to do to get her out of the nest and back to her own coop is to stick the swatter into the pop hole. One glance at the swatter and Edith is out of the nest like a bullet out of a rifle.
I'm still amazed at how effective a simple fly swatter is in disciplining a bully chicken. Give it a try.
