Male or Female Rouen Duck?

I just can't tell...please help.

I'm about 50% sure that it's a boy duck, but not certain. You can tell in a few weeks, if the voice stays high and reedy sounding, it's a boy, if the voice gets low and raspy and sounds like a quack, then it's a girl duck.

It's too young to tell.
You'll be able to sex by voice when it is around 6 weeks or so. Some quack early, others take longer. But if you hear quacking, it is a girl. If it is a raspy sound that isn't a quack, it is a boy.

Our roAuen ducks look identical but

one quacks and the other squeaks. Are they both female?
