I have no bullies. I keep lots of chickens, currently 93. A large shed, lots of range, and options for where birds can go and hang out makes it very peaceful....
... So far I have not had bullying issues in any of the 200ish birds I've owned. Give your birds enough space and they will be rare.
Remember that hens can only recognise about 100 other hens and to bully another hen, the aggressor hen has to recognise her. This is one reason that you can house 1,000s of hens in one hen house on a commercial poultry farm and not have 100s of so called bully hens to contend with.
