Rusty red duck?

I realize it's early but a pair of the mixed ducks I hatched have developed an interesting color and I'm curious if anyone has seen it. Best I can figure is they're khaki and runner cross based on their features.
I have a khaki drake and runner/pekin/khaki/rouen/cayuga/rouen+mallard ducks.
