If the bunny is just that, a bunny, you should give him time to adjust to eating solids. Often, when a newborn starts solids, they go through a period where they get a little constipated, it's natural.
The water however is a different matter. Do you have a bottle that he can drink out of? They don't typically like to drink from bowls, and they knock them over all the time. I would give him a day or two to adjust to his surroundings, and see if he settles in a little more, but after that you see that it's still going on, then I would take him to the vet. Hope this helps, good luck.
