Mine goes after my buttons.
I had a pullet fly up to my shoulder and peck at my tooth one day. She kept looking at my face and I would smile at her, thinking she was just wanting to be sociable. Then she pecked at my tooth. My husband told me later that I had a piece of spinach from our lunch salad in my teeth, but he didn't want to say anything. Thanks a lot, the chicken had to help me out! Lol!
