If the thermometers you have are the ones I'm thinking of (the dial ones), I'd ditch them. They aren't very accurate. I'd try an Acurite Indoor/Outdoor thermometer with a probe. They are about $13 at Walmart, and they will give the temperature on the hot side and cold side, and humidity. I'd also ditch the half log, and give her 2 hides with only one opening on each. She should fit snugly inside. Put one on the cold side and one on the hot side. I try to maintain mid 70's to 80 degrees on the cold side, and about 88-92 degrees on the hot side. Is your heat source regulated? It should be on a thermostat so she doesn't get burned! You can order a hydrofarm off EBay for $25-30. (Or a Herpstat if you're willing to spend that much). Hydrofarms aren't the best, but they are definitely better than nothing!
She does not need to be moved out of her habitat for feeding- cage aggression is a myth.
I try to keep my humidity between 55 and 65, more when they're in shed.
Hopefully someone with more experience than me will chime in, and correct me if I'm wrong about any of this!
