Question about sexing

[CrazyFowlFreak]

I have five ducks, I know the BEI is a girl, for sure. I also have two Khaki Campbells and two Blue Swedish.

On the Khaki's, Caramel is a lighter khaki and Mocha is darker. Caramel has orange legs and Mocha has brownish. The brownish legs mean girl, correct?

With the Swede's, Forest has a greenish bill and Corn has a blackish grey bill. Both have dark legs.

What sexes do you think they are?
Thanks!

How old are they? I don't know about those specific breeds, but all mallard derivatives can be sexed by voice around 4-6 weeks. The girls will develop the loud, characteristic "quack" that ducks are famous for. The boys will eventually develop a low, raspy murmur, but they will still just be peeping at 4-6 weeks (their grown-up voice develops later than the girls).

Boys will also develop a curly tail feather at sexual maturity, but it's not always obvious and can be lost during a molt. But curlies are definitely boys.
