Can anyone help with gender please?

Hi, wonder if anyone can help with sexing my ducks? They all sound the same, however, when I got them the breeder thought they were 1 drake (dark one) and 2 females. The black one has green throughout the feathers. The medium brown one and the black one has a purple/blue streak on the wing feathers.
They are 17/18weeks now.
Sorry I’m new to all this.

Do they quack loudly or make quiet noises

I think they are all quiet but after watching some videos on YouTube they don’t sound like either. They seem to be cheeping still not quaking or rasping!

Would it be better if I try and upload a video of the noise they make?
