Barred vs rippled in Muscovy ducks?

Yeah, the white-head gene is an odd one, where the ducklings and young will have solid coloured heads that then turn white. On babies, you can tell if they have this by them having a light coloured spot at the back edge of the eye. It's dominant, so difficult to get rid of it trying to breed for a solid colour.

I think one of my chocolate gals has that. Her head is almost completely white now
