Gender?

[Pra0319]

Can anyone tell the gender of these 2? They are both 10 weeks old. One is a Dark Campbell and one is a mallard.

Easiest way to tell is by sound but they kinda look like hens to me.
They quack loudly they are hens. The just kinda mummer they are drakes.

The mallard is quiet but the Campbell kinda sounds like it quacks...but they have a slight dark green head and they look like they are starting to get lighter grey feathers on their body’s? So I’m not sure
