Runny poop stuck to her butt

Question
I recently got a baby dwarf rabbit (approx. 2 months old). I've had her for about a week now and lately she's been having runny poop. Its getting stuck to her butt and to my other rabbit. She appears to be in fine health. She is eating and drinking and playing with my other rabbit like nothing is wrong. I thought maybe it was because I gave her a few too many treats so I stopped, and her poop was hard again but when I woke up the next morning, it was runny again. Help? :(

Answer
Does she get as much fresh timothy or grass hay as she wants? That is very important in a rabbit's diet. Netherland Dwarfs seem to be particularly prone to the runny feces, so the hay is even more important.

What type of treats do you feed? Do you get pet store food (usually poor quality, and anything but pellets in the bagged food is usually bad for the rabbit) or a higher quality food?

Get back to me on these, and I can tell you what is the most likely cause of her problem. :)
