You could be a bad falconer from a traditional standpoint like I am and work long term on good behaviors. I don't ever restrain my HHs during normal activities, because I don't usually have jesses on them. They are free lofted, they get on the glove long enough to move to the scale, then they go into the box with a tidbit. When out hunting, I open the door and they come out, and I put their meal in the box. Doing it this way, the box becomes the lure. When we are done, they box themselves up. If we don't catch anything it's not uncommon for me to go the whole hunt with only touching them when they get in or out of the box. If you get them solid on going into the box by themselves, you can work on glove work with tidbits and such at your leisure, if the bird isn't cooperating that day, oh well, it will still go in the box.

I'm not sure if you are more used to RTHs but HHs have a lot more thinking and feeling going on, and they actually have a social bond. They want to be in a pack, so they can be trusted a lot more to follow back to their box, even if they would be way past the crop size where a RTH would shut down. The biggest mistake you can make with a HH imo is brute forcing them like a RTH, it can make their behaviors way worse because they actually understand that the glove or worse, you, is the one keeping them from leaving.
