Buns do tend to drink more out of a bowl,so it's great she is drinking,and also great she is eating.
Make sure she has lots of fresh hay, give her fresh hay every hour or so. You could try cutting up some of the hay into tiny pieces and mixing it in with the food, but hopefully, the more she feels comfortable there, the more she will eat, You can try putting her food bowl in a place she feels safe, or drapping a towel or something covering the area so she feels safe.
I have also found that 'accidently' scattering a little bit of food around will encourage mine to eat because they seem to think it is naughty and that makes it far more fun. If mine have been off their food I will strategically place the bag around and more often than not I will see them with their head stuck in the bag munching away.
Good luck, you're doing a great job!
