My guineas are still locked in their coop, pre-release. I was in there today to stir their bedding a little and they freaked out, wouldn't stay up on their perch out of the way and started flying around. One decided my head looked like a good spot and ended up scratching the devil out of my face when she realized mid-landing, what she was about to land on. Superficial scratches but they look pretty ferocious. Should make an interesting story when people ask!
