The pied stuff can be confusing... it feels like you could take white and another color and get a mix like making a marbled cake out of two different types of batter... but it's kinda it's own thing. You need a bird with the pied pattern thrown into the mix.

India Blue x White will produce India Blues split to white. These will likely have a few white feather (usually at the tips of the wings or on the throat).
Pied is a different allele on the white gene... I think chicks need a copy of both the white and pied genetics to exhibit the pied...
