I have a brown leghorn that is named Trixie but we call her "the mean one". She too was terrorizing the other girls and I separated her for a full week and it didn't help. I finally went to the store and bought a squirt gun. I sat outside the coop with a book for a few days and when she started to be mean I sprayed her. She got to where as soon as she saw me lift up the gun she would run inside the coop to hide. She is nice now
. It took effort on my part, but fortunatly it was summer time and we have beautiful weather here so it wasn't a hardship to do it.
