Like Jay stated it can take as little as a year with luck..pewter h pied male can easily be ready for the next year...plug that to the female and prey to the ball python gods...I say this route cause pieds are out there already but not many pewter pieds and its also a multiple gene snake....simple gene snakes are becoming a thing of the past.......Again nothing wrong with an entire batch of pieds but you have to be ahead of the game with so many people into ball pythons....just my 0.02 cents...
