Rouen duck gender

[Bubba Ray]

Ok I am completely new to raising poultry and decided to get some Rouen ducks. I always liked them. Any wat to tell sex at an early age ? I got 3 chicks and I am not concerned about sex just curious. I suppose if any heads turn green eventually I will know for sure. Any clues at a youger age ?

They are too young to determine gender by sight at this age.
at 10 weeks you can tell by sound. Usually by 8 weeks girls will start giving you an idea. They are more vocal.
at 12-14 weeks males will have drake feather - curled feather at top of tail.
