That is great news. Make sure she doesn't eat the wallpaper as the paste can be very poisonous to rabbits. You can use a pet spray called bitter apple which has a nasty taste and deters animals from chewing.
Alterinitively, get a childs water pistol and squirt her everytime she does it. It will not stress her, and is beter than shouting at her and giving her the attention she craves when being bad.
Make sure the pellets you give her at the moment,are the same brand,but are higher in calories just to get her weight back up. It is better that than overfeeding and upsetting her tummy again.
