The problem is that your Pied is a male and you only have a Het. Pied female, so do you breed the male Pied or the Pastel Het. Pied male to the female? It's either that or fork out a few bucks on a breeder sized Pastel/Het. Pied female.
Well if your a gambler got het x het however if your not lucky and don't hit on those odds you will be left with a bunch if babies that are not worth very much as far as business goes.
