I have a Salmon Faverolle pullet who won't stop picking 3 of my other pullets. I have tried giving them more space, food, and I even applied Blu-Kote but it isn't working. Every time she goes near the 3 EEs she rips their feathers out and eats them. No other bird is doing this. I am trying to get rid of her, but having no luck. I need help!!!
