I got my first Cornsnake last May as a hatchling and the first thing I noticed about him was that he was just as happy curling up under the aspen as he was in the hides. Now hes over 2 ft long and still tunnels around in there as much as he uses his hides. I wouldnt worry too much about it. The first 6 months of Ransom's life I only saw him in the middle of the night or feeding/holding times. Now I walk in and hes hanging out on limbs in the middle of the day.
