Indian runner duckling colours as adults

[Cluck0FF]

Hi my runners are hatching today. I bought the eggs online so didn't see the parents. They came from a selection of white and green eggs.

Does duckling colours signify adult colours? I'm assuming you can't determine sex from colour when you haven't seen the parents.

Thanks

You can get an indication of what colors they’ll be but some look similar as ducklings. From the picture, the one on the bottom left looks like it’ll be chocolate, the two yellow ones will likely be white, and the one on the top right I’m not sure about.

Just a guess, Two Silvers, One Gray, and One Blue Bibbed.

The reason I said silver instead of white, is because White Runner Ducklings should have orange bills.
