A het pied x normal = 50% possible het pied babies.
In other words, half the hatchlings will carry the pied gene. THey will all look normal. Keeping all the babies and breeding them back to the het pied, you may get a pied out of one or more of them, but that's after raiseing them up to breeding size.
And that's IF your python IS a het pied.
