One of my three 8 month old RIRs is getting continually more difficult. She immediately starts pecking at me when i enter the coop. I usually use a hoe to make her stand still, then I pick her up. She is fine with being picked up. But I cant do anything in the coop for fear of her attacking me. The minute i put her down she is after me, pecking at me enough to draw blood. I want to have neighborhood kids collect the eggs while we are on vacation but I dont trust her. I am not sure what to do- any advice?
