I would watch her very closely. Hopefully she didn't actually ingest it, but if she did, it could block her digestive track, which is very serious! As long as she continues to eat, drink and poop and seems normal, you should be good. If she stops eating or pooping, then things are very serious. You may want to research small animal vets in your area if you don't already have one. I'm not sure if they would do surgery or what, surgery is the norm for dogs/cats, but rabbits are more sensitve. You may even call the vet and just talk to the doctor and see what they recommend.
Hopefully your bunny will be fine!!
