Crossing fingers for you! My bp eats regularly, but she requires a little privacy and ambiance to get in the mood to feed. I've learned with her to wait until later in the evening when she's likely to be "awake" and cruising around. I place the feeder in her tub without bothering her, throw a towel over her tub and walk away and listen for the tell-tale strike/squeak, and then wait a little longer before I check that she's got the meal down with no issue. And I've also learned that feeding her in a separate tub is a no-go. She spends all of her time cruising around the tub looking for a way out and ignores the prey item.

As for ambient heat - lots of thoughts about that, some ideas may be better than others for your set-up. Me personally, I run a Lasco (or is it Lasko?) electric heater in the room to keep room temps about 75-76, since that room can drop into the low 60s without the supplemental heat in the winter. I think what you've described so far is just fine. Maybe see if you can experiment with humidity in the future to have the ability to provide more humidity going into shed.
