Im sure its because of her height. My Grandaughter stands about 2 and half ft tall. When she comes to visit, they run up to her and start to peck at her. The same way they do my cats. Please send some ideas in how to break my chickens of this behavior? I want them to treat her the way they do every one else, which is friendly. I see it as, if you can break habits of dogs and cats, it can be done with chickens. I dont think I should lock them up when she visits. She loves them.
