Hello,
This can happen, unfortunately. Were the crickets possibly too large for her?
Do you feed her in her tank or do you place them in a plastic bin to feed her? Try just
putting a few out for her at a time, so it doesn't overwhelm her. I know she's an adult,
but maybe she might prefer smaller crickets, but I'm just guessing.
Does she interact with you outside of feeding times with you?
