Once the baby snake puts a slit in the egg...

how long till it is out of the egg?

Can be as quick as a few hours, or as long as three days or so... Depends really. If you are in doubt of its livelihood, POKE it. It should respond by moving at your touch.

how long till it is totally separated from the egg?

Once it is completely out, the umbilicus should have already seperated. There may be a bit of yolk attached still, depending. Leave it be, it will fall off on its own.


how long till the first shed?

A week or two, depending again on several things.
