@Oxalis Thanks Oxalis. Within the range of "normal" redfoot keeping, each one is such an individual, with individual food, sleeping and human interaction preferences.
This baby loves being at the higher end of her temperature range, actually- and I often find her between 87F - 92F, even though the cool end of her habitat goes as low as 82F. (I have a juvenile that stays at 78F - 82F, and another bigger redfoot that doesn't seem to care one way or the other...)
