Identifying young ducks

[wyoducks]

Hi! I’m new to this forum! I’m searching assistants on identifying my 3 young ducks. I got them as duckling from a feed store but they were unsure of the breed. They are 8 weeks old now. I need help identifying their gender and breed. Thanks!
I attached some pictures I took today (8 weeks old) and some from duckling and one from somewhere in the middle

I think Khaki Campbell. Females will have a loud quack. Drakes have a lot less volume and sound raspy. Pick them up; if loud-female.

Just looking at the pictures, I'd guess two drakes and a hen-going by the rump color. On drakes the rump becomes black, while hens have brown.
