We have 9 chickens or varying breeds and two ducks, our first flock. The Leghorns have been, for the most part, the dominant ones since they were chicks. In the past few days, however, they have become a bit violent towards our Ameraucana, who is quite docile. They have pecked out the feathers on one side of her neck, leaving bare flesh and a little (very little) blood. Other than seperate housing (not a possibilty in our situation), does anyone have any advice? Can the Leghorns be trained not to attack her? Thanks for your help!
