If Appleyards are to the SOP, they both have a dark bean on the tip of the bill. Drakes have yellow to greenish yellow bill. Ducks have yellowish orange to brownish orange bill.
I don't remember at what age the bill color difference was noticeable, but it was well before you could feather sex.
I've seen enough Appleyards that aren't to the SOP, that I urge caution about using the bill color to sex young Appleyards.
