hungba, sounds like you're on the right track with this girl. She might just need a little more time to get over the relocation. She's at 1000 grams, so it's not like she doesn't know how to eat.

I think leaving a F/T on top of her hide over night might be a good idea.

What kid of tubs do you use? If you use IRIS MCB-L's they sell one that's blue tinted. I've used it with success for skittish juvies.
