I probe my ball pythons and I will also sometimes pop the hatchlings (although I never pop adults as I don't feel comfortable doing so) but I don't think i'd feel comfortable probing a young corn snake. I have popped numerous corn snakes but I'd say if you don't feel comfortable popping, find someone who does that you trust and have them do it for you. I know some may feel comfortable probing a young corn but I don't so I don't recommend it!
