Rouen and khaki, boys or gals?

[ErinDO83]

8 weeks old trying to decide what I've got here? Any ideas? Kinda thinkin the rouen is a gal. Not sure about the khaki, it's my first one.

Do they both make loud quacking noises?

The Khaki looks like a female to me. I am not as good at Rouens but I am guessing male. The Khaki has two-toned feathers. Is she quaking loudly?

Yay! They are pretty loud.

Not positive that rouens have this in common with mallards or not, but with mallards, I am able to tell hens from drakes around 6 weeks old simply by how dark their heads are. Males are darker than females, I’ve attached a picture for reference. Female on the left, male on the right
