Try baiting her with some soft food, and see if she'll eat at least a little, and keep the water handy for her. Another thing you might want to try is giving her some fresh picked grass, they tend to eat it when their stomachs are irritated.
If it goes on much longer though, get her to the vet, it could be a cold, or something more serious in her stomach. Hope this helps, good luck.
