I have a little mutt banty hen, Clover. I have a lot of bantams and large-sized chickens together, and there was never a problem before I got a new Buff Orp, Buffy. She bullies Clover, and she literally grabs Clover by the hackles and shakes her. I have Clover quarantined even though she's not hurt, I just don't want her to get hurt. What should I do? Should I get rid of Buffy?
