My six year old RES generally hibernates in the loose soil outside of my pond like he has for the last few years. It has been continuously below 32 degrees for 10-16 hour stretches. As cold as 19degrees F. It hasn't been this cold in the 5 or so years he has been out there. The pond nd is in the Sierra Nevada foothills at about 1800 ft. Yesterday I was looking at his hibernation spot and his Burrow looked like it was collapsed or he had come to the surface. I touched his shell and he responded by shimying or wiggling a little, so I know he is still alive. He is about two inches below the surface of the soil with about a third of his carapace covered. Is it possible he came out of hibernation to "come to the surface" to get warm?
Do you think I should bring him inside to a indoor hibernation set-up? Or, do you think he will make it since he has made it so far?
Thanks
