Hatchling #2 certainly has the "classic" belly markings of a het pied. The ones that everyone says means a het pied, but to my knowledge it's never been conclusively proven.

However, I said #1. I can't put my finger on what it is about that hatchling, call it a gut instinct if you will, I think that one is a het.

Number 3 is certainly attractively marked, het pied or not.

And number 4 ? That thing almost looks pastel or fire-ish to me. I love how bright and crisp and clean it is.
