What kind of pellets?
Sometimes youjust have to experiment.Some bunnies will haveit clear up by changing brands, some by cuttingthe pellets out altogetherand just feeding a lot of veggies (and it takes a lot), others do better with highfiberpellets and noveggies at all, and all points between. Sometimes a few rolled oats help. (Sometimes they cause it). Have you tried a little canned pumpkin?
There arethreads from memberson that page I linked to, you should read through them and get an idea ofwhat worked for different people. It really is all over the map.
