Sexing My Ducklings?

[April and Andy]

One of my Cayuga ducklings is jet black and much skinner than the other (April), while the other (Andy) has some white/light tan around his chest and beak and is a bit bulkier with thicker legs, which makes me think they are two different sexes. I read somewhere a long time ago that the lighter colored ones are more commonly male, just curious what everyone thinks about the legitimacy of this? I was hoping to have one drake and one hen so that would be so awesome!

How old are they? If one has a loud quack it's a girl and if it sounds like a raspy frog it's a drake.

They are three weeks. So far they both sound pretty squeaky and not much quacking

You'll def hear the distinct semi quack - like a fart and a belch - it's kinda funny-- from the girl- at approx 6 to 8 wks -- and also a tad later the drake will be whistling etc if they are separated or w/ any stress but no quack.
