I know there is often discussion on distinguishing the differences between Dark Pied and Split to White. I have seen several photos of single gene white-eyed (shows only some white ocelli) and double gene white-eyed (shows almost all white ocelli). The chicks seem to show characteristics of a split to white or a dark pied. I was curious if there is any identifiable differences between young birds (say up to 12 months) of white-eyed and the others? I know I am complicating things, but what about a bird carrying the pied gene (single or double copy) and the white eyed gene and no white gene?
