What do you mean "they get stuff"?My issue is I'm so slow that they get stuff before I'm done plucking usually, let alone getting everything out and I can hardly maneuver them.
What I do is a bit more hands on. I actually lay the duck on the ground and sit on them (lightly but firmly, to keep them from flapping). I stretch out their neck by holding on to the head, hand over the eyes to calm them, and speak gently to them. It's a very personal experience, but I feel better being this close and giving them some sort of comfort.
