As Jen stated above, try feeding her in her own enclosure. The simple task of relocating her to a feed box may be upsetting her and could be the cause of her not eating. Also make sure everything is thoroughly thawed out and heated properly so she's attracted. If all else fails then if you know she eats live try that to get her back to eating then you can attempt F/T again. I've seen BP's that prefer certain colors and God knows what else as they can be picky eaters.
