Tom said:These three babies perked up out in the sun today and now they are back in a "conventional" set up. They seem to be perfectly fine now, but I am not willing to risk it. Hmm, now that I think about it these babies seemed to be favoring sitting in the sun a lot lately, even on hot days, when all the other babies hid out in the shade in their respective sunning enclosures. All the sunning enclosures are side by side and subject to the same conditions, but I almost always found these guys sitting in direct sunlight, right next to the shade. Maybe 92 just isn't warm enough for long term health on sulcatas. They seemed to be craving more warmth than my other 15 hatchlings whenever they were outside.
If this is true then it is more torwards what I would recommend...and that is to allow them to heat up as much as they want with a range of temps. They may not need the higher heat every day or often, but when they want it, they should have it.
Good work, Tom.
