I've used clicker training to do behavioral training for older horses to picking up hooves. It's really effective and even novice horse owners find it easy. Horses like it because of the treats, lol.
Here's a video I found that shows you how to do it, I'm sure you don't have to move as slowly or as quickly in the video. Go by whatever level your horse is at. Although in my experience the horse usually understands the "game" in about 5 or 6 successful pick ups.
I've found that horses that give trouble with the front hooves don't fight as much with the hind ones.
I hope you can get the hooves done ASAP!
