Are her fecal poops normal or are they coming out soft? If she is having soft fecals or if you are seeing her cecotropes and they don't look like the normal cluster of grapes, you may need to cut back on her pellets. I know at this age that they are supposed to have unlimited pellets, but sometimes for some rabbits, that just doesn't work out because they have a more sensitive digestive system. I have a little doe about the same age and she would always have a few soft poops everyday. So I started to cut back on her pellets and she started having less of the soft poops, and when I tried to give her more pellets, she would have a lot more soft poops. So now she gets about a tablespoon of pellets a day and a little alfalfa hay, and as much timothy as she wants. Now I don't see soft poops from her as often. Giving sugary treats can also cause the digestive problems, and a few veggies too. So it really just depends on your individual rabbit, as to what is going to be best to feed her.
Now if you had recently just fed her something different that she doesn't normally get, and then this happened shortly afterward, then I would say that it was probably whatever you fed her that caused the problem, but if she was just getting her usual food and nothing new, then in these cases it is almost always caused by excess carbs and sugars causing the digestive problems, either from too many treats, or from too many carbs and sugars that are in the pellets she's getting. The best way to solve it is to cut out treats if you are feeding them and see if that helps. If you aren't feeding treats, then it will be the pellets causing the problem, so you should cut back on the pellets and see if that helps. You just always make sure that she always has lots of hay to eat. Hay is the best thing for digestive problems.
One other possibility, especially if changing the diet doesn't help, is that it could be parasites or bacteria causing the digestive problems. In that case you would need to take your rabbit into the vet to get the right medicine for her.
I'm glad she's eating again and feeling better
