My ladies miss their mark sometimes when they're going for treats and hit my finger. It doesn't hurt - just startles me a bit. The other day, though, one girl got upset with me and literally grabbed the top of my hand with her beak and wouldn't let go. (I was moving her at bedtime, and she was none too pleased.) Anyway, we had a staring contest while she held on the top of my hand with her beak. I won, and she let go. I had a small bruise but nothing more. She's a noisy RIR named Jane - I wouldn't give her up for the world.
