I had never noticed their "what's hatching" site before. So it sounds like they bred a clown to a female that they later found out was a het pied to produce the double het parents of this baby. Wish they had pics of the parents up to see how normal they are or not but this baby does seem to prove that piebald and clown are not alleles but rather different mutations of different genes as generally expected. Years and years ago someone named Matt Turner produced a pied from breeding a male purchased as a het clown to a presumed normal so that had me wondering if there was a relationship there.
Maybe not as dramatic a cross as we'd hope for, but I think it looks pretty hot! The clown pattern does have some influence over the pied pattern (the part you can see) and I love that it keeps the pied look, as opposed to the spider pieds that leave you with essentially a solid white snake.
