I would move her cage to a very quite area, and not mess with her too much, besides feeding, and minimize cleaning as much as possible. Also don't pick her up for now, if you don't have to. You can also try a small amount of treats. Normally I wouldn't recommned feeding treats to a baby bunny, but in a situation like this it is sometimes needed to help a rabbit adjust to it's new home. So maybe try a less sugary treat like a tiny piece of carrot, or a few pieces of rolled oats. Some rabbits respond really well to treats. If she doesn't, try to just leave her alone as much as you can, but also you need to check in on her to make sure she is eating, drinking and pooping. You could also try covering most of the cage with a towel and just leave the front uncovered, so that she feels more safe. If she stops eating and pooping, you'll need to take her to the vet so she doesn't develop a blockage.
