Could you lure them into a pet carrier to get them to the run? My 2 have a large run attached to their hutch but they've been going into a bigger one on the grass. They hate being picked up so we've started doing the transportation via their carrier. (cunningly let them get used to it as a good thing before they go for the vaccinations and health checks shortly). Unfortunately I've no medical knowledge but am sure if your buns still running about she should be ok. My first ever rabbit used to jump out of her hutch to the lawn and it was about 3ft of the ground.
