I think so. Some of the Pastel het Pieds we have look a bit different, as well as the Pewter Pieds. Seems the pied gene causes striping in Pewters. If I think about it, I'll try to get pics of the cinny pos. het Pieds we have from the same clutch as the Super Pewters. One looks different, the other looks like a typical cinny. The Super Pastel from that clutch look unlike any Super Pastel we've ever seen. We THINK it's from the pied gene. Only time will tell.
