i use flour when that happens, on one of my girls, i have to be real careful wrap her in a towel and hold her head still covering her eyes- she will jerk just at the right moment otherwiseI just cut chuck's beak back a little too far and made her bleed. Thank goodness that (a) I didn't cut all the way, so it's not gushing and should close up and (b) I had styptic powder on hand, nearby, and opened.
Lesson learned: if it seems to be causing her discomfort, it probably is, and I should stop.
Taking a deep breath. I don't like hurting my girls!
