Silver Apple Yard Ducklings

[sktlmt]

I have 11 silver appleyard ducklings. They are 2 weeks old and are now enjoying the sunshine. At what age will I be able to sex them? There are a few that are much larger and wonder if they are drakes. In my 11 I got 7 with the classic appleyard pattern 2 that are pure yellow/white and 2 that have more black on their backs.

I also have Silver Appleyard....Cute Ducklings....You will be able to sex them once their voice changes..That happens around 8 weeks old...Sometimes you can earlier with Drakes because they will start getting the classic green feathers coming in on their heads and a white collar...
