My corn is about 4 months old now.. She has a rock on the warm side and a water dish on the cool side. Lately all she does is go under the water dish which isn't small it's pretty heavy she goes under there and moves the bedding and lays right on the glass and she's cool to the touch. She has always gone under there but not usually for very long her skin is discolored and has been for about a week. I haven't seen her come out in a week she has been under the water dish. She seems healthy when I hold her and she ate two pinkies last night so apparently she's okay but why the hiding under there all the sudden? After she ate last night she went to the warm side obviously to digest. I know she's about to shed does this have anything to do with it?
