Give it a couple of days. Sometimes rabbits just get in weird moods (like the rest of us) and do not want to eat or drink much. It normally goes away and they are back to normal in a day or 2. My girls did not even eat 1/2 of their veggies last night and did not finish their pellets. I got a little worried but they were back to normal this evening. If she is not back to normal in a couple of days then I would be worried.
