If you are having problems syringe feeding her,and she still won't drink, try sitting her on a towel and wrap it around her firmly so she cannot kick out. You must keep up the fluids.
A good remedy for blocked tummys is pineapple juice. The enzymes it break down the blockage and get the tummy working again.
Other than a generally blocked tummy, If when she goes to the toilet the is clear jelly in the poos it could be mucoid enteritis so keep an eye out for that in her bedding.
Mucoid enteritis is quite common in rabbits and if not treated will kill her.
Also donot confine her to her cage on any account. She needs to be exercised so that the gut will start working, and also so she does not get depressed
