no. i dont think you can probe them as babies*but im not sure of that*. but you can "pop" them. this is exposing the hemipenis (or lack of)
heres an artical on it. but i wouldnt do it yourself unless someone can personally show you how to do it.reading about it really isnt good enough.
people at pet stores like petco, and places like it, wouldnt know how to do it. someone at a reptile specialty store, or a vet would probably know how to pop baby snakes.

i think everyone should read that. because theres a pic where they popped an adult burm using some chemical. anyway...its impressive. rofl.
