Crating actually accomplishes two things. It removes the bully out of the pecking order so she doesn't get a chance to continue her behavior, obviously. But it also gives the target a respite and helps build her confidence. It completely resets the pecking order. But that won't happen overnight. That's why crating the bully for 3 to 4 days/ nights seems to work so well. Our bully was at her worst at roosting time, so she got crated at night for sure. Glad yours is improving!
