EDIT FIRST before first: WELCOME TO THE FORUM and thank you for helping this baby!
first: you need to get a weight before you toss food at them.
second: i'd advise against rushing to the vet. the vet is a very stressful experience for a beep and might do more harm than good right now. IMO I'd just give her a week or two to relax in good keeping and maybe see if she'll eat.
then we go from there.
looking forward to pics...
