Personally, I would refreeze and feed in a few days. I would also leave her in complete quiet with no activity for a few hours post feeding. She will be more likely to eat without seeing someone walk past, even if it takes putting a towel over her tank. And no peaking!
You don't have to move the hide, I would just wiggle the feeder in the hide entrance and let her strike however she wants.
Let us know how it goes!
