I feed Gary crasins. He has the sweetest little squeek like "don't eat me, I'm a baby!" and thrashes around. I put him on his back and hand him a crasin. As long as he's chewing he stays still so I can clip. It takes a crasin per paw, but it's worth bribing to get cooperation. With this method he has gotten much calmer over the last few months so it is getting easier.
The rest of my buns have learned handling = treats so they don't struggle when I pick them up.
