Is there a good temp guideline for when my juvenile CDTs should stay out and when they should come in at night? I've been using 65 degrees as the cutoff where I bring em in, based on nothing but a hunch. In general, they seem a lot happier when left to sleep outside in their burrow, but I don't want to let them get too cold. (A couple weeks ago they started yawning a lot, so I worried about a respiratory infection. I started bringing them in at night and the yawning stopped.)
