I’m assuming one parent was white and the other snowy? If one was snowy are they golden or silver snowy?View attachment 3419976
Both eggs aircells look like this.
It is possible that they’re yellow, they’re 3/4 pekin and 1/4 welsh harlequin. Or they could be multicolored.
If one parent is white and the other golden snowy then you will have sex linked ducklings with the females being chocolate mallard and the males regular mallard coloring. If one parent is silver snowy and the other white then both male and female will be regular mallard color.
