If there is one bully, separate the bully as it will lower her in the pecking order.
You can put pinless peepers (blinders) on the bullies as well. They won't be able to see right in front of them to peck...some people have success with that.
Rooster Booster pick no more lotion tastes bad to them but must be reapplied daily...I have only used that with chicks though and don't know how effective it is with adults.
When they get hungry they will eat...I would just fill the feeder and not put the feed on the ground. Feed on the ground may go moldy and moldy feed can kill chickens.
