I am pretty inexperienced as I only have one corn so can't really say what normal is. However my one corn, Spotty, is about 10 months old now and the only way I ever have any indication he has been out of his hide is the evidence he sometimes leaves in the water dish. I peek at his viv from the doorway of the room he is in several times throughout the night as I am up with a newborn foster baby feeding her, her bottle and I see nothing. Spotty is healthy and moves great when I handle him and put him in a critter cage to eat, very determined to find a way out of the critter cage whether he has a full belly or empty belly. Maybe some corns are just like that and don't come out much. I don't know.
