i have a baby corn and it hasnt shed since i got him a few weeks ago. it looks like he is ready to shed, but his outter skin seems to be flaking off in small small pieces, and at a very very slow rate. anyone have any ideas as to what might be wrong here? i constantly see him rubbing against the rough stone i have in there trying to shed but it just seems to flake off, with hardly a noticable amount of shedding.
