I have a pullet that is pecking the others to the point of drawing blood. It's just one of 16 chickens pecking. I'm feeding a 18% layer ration (has animal protein), scratch with BOSS, suet cake, oyster shells, egg shells, and water. I have tried clipping the very tip of her beak and that didn't stop her-I won't debeak so please don't suggest that. Any ideas on why she is pecking or what to do?
