Duck ID

My step mother got these two as ducklings at TSC. Does anyone have any ideas on their breeds? Sorry for the poor photo quality. Her camera isn't great

Looks like a Rouen and Khaki Campbell to me.

Is there anyway to tell their sexes? Thank you!

How old are they? Do they quack or make a raspy kind of sound?
If they quack they are girls. Drakes make a raspy sound.
