Could coloring be sex linked? Rouen/Blue Swedish crosses

[RavenousAK]

My egg ducks have decided they are meat producers this summer... endless secret nests. I have one Drake. He is a Blue Swedish. I have 2 Rouens and 2 Gold Star Hybrids. One Rouen nest has hatched (the three in my profile picture) and one Gold has hatched a nest. There are 3 more nests out in the grass (1st Rouen has already made another nest).

Of the ducklings that have hatched they are Dark with a yellow bib or they are blonde with the blue/grey beak.

Is there any possibility the coloring could be sex linked? I know it is wishful thinking, but I figure if anyone knows it would be someone on this site. If they are it would help me plan what to do with all the buggers. I am looking at 50-60 of them by fall at this rate.

NOTE- the 1st rouen put her nest in an idiotic spot and I wound up finishing hers in an incubator. Irritating but have the coolest hatching pictures.

I'd probably just guess that you have two (or so) colour possibilities from the parents, so they throw those two colours. Do you have some closer pics of the moms?

No, no chance that they are sex-linked given your drake. If you want sex-linked ducks in the future, you need a drake that expresses chocolate (such as a khaki campbell), and ducks (such as rouen) that do not.
