How high is the bed? As a rule of thumb, if a bunny jumps up somewhere on its own, they usually can jump down safely. But accidents can still happen.

She could be afraid of being handled as well, or something unrelated could be going on. Will she take a treat or eat any favorite greens?

It’s good she will eat from you hand, I would be sure to keep an eye on her eating and pooping. Especially encourage hay. If she isn’t near her water and litter box, you might want to either move her over to them, or move them over to her. That way if she’s in any pain she won’t need to travel as far to get to them.

It’s also possible she’s having a bit of gas or something like that.

You can try some Simethicone in case it’s gas. I hope she feels better soon! Is she pressing her belly to the floor at all?

A vet assessment is the best bet to figure out if it was a temporary “Ow, I need a minute” or if there is a sprain that needs to be monitored… or if there is a fracture/break. At the vet appointment, your vet should be able to narrow down the possibilities and you may need to do an X-ray if it is not clear.

I will share a recent experience where my rabbit Wick actually took a fall and was holding his left paw up. The vet said that she believed if was likely just a sprain/muscle-injury, but she couldn’t know exactly. We opted for the X-ray, and we were very glad to do that because he ended up having a complete fracture of a finger (he broke his middle finger), and that heavily changed what his treatment would be as a result.

I will note that rabbits can instinctively hide they’re in pain, so while it’s great she has energy, just be aware that it could still be something worth formally assessing. For my Wick, he has acted literally 100% the same from before the break to now during recovery. He still tries to dig even though he literally cleanly broke a finger.
