I have a small flock that consists of 2 EEs, 1 blue cochin, and 1 speckled sussex. More and more lately, I've been having problems with my speckled sussex, Lucy, bullying the blue cochin, Violet. Violet has always been a little of an outcast, but nothing I've been too concerned about. Lately though, every time Lucy and the Violet get near each other, Lucy jumps on top of her and comes up with a beak full of feathers. If I see it's about to happen, I push Lucy back but she keeps relentlessly trying to jump at Violet. There hasn't been any blood or bald spots (yet). Is there a way to stop this behavior before it gets any worse?
