Khaki Campbell gender?

[Momma*chicken]

So we have 6 Khaki campbell ducklings that are almost 10 weeks old. So far they all look the same. At what age do they start getting their adult feathers? I know the Drakes get greenish black heads. Is it possible I got blessed with all hens?

I'd post a Pic, but I'm not home at the moment

Sorry, but the drakes do not get their breeding plumage until around 3 months old. Until then they look very similar. But, there is one major difference. The girls have two-toned, usually lighter feathers above their tails and the drakes have solid, darker feathers above theirs. Here are two of my ducks at about 7 weeks old.

They also have voice differences at this age. Girls will have the loud quack "wack wack", like a duck call and the boys make a softer, whispering "wap, wap, wap", like they have a sore throat.

If you still aren't sure, post a picture when you get home and we will help you. I hope you do have mostly girls.

Thank you for your help!
Yes about the sound they make I do know about that, but it's so hard to catch them. They all herd together. I hear tons of quacking and only a little wheezing. However, I've got some Pekin ducks the same age flocking with them that we have a couple Drakes so Idk if the wheezing I hear is from the Pekins.

I got a few pix last night but it was getting dark and they wouldn't stop moving lol. So the pix aren't super clear

If you can get a closer shot of their backs, it would help. If I had to guess, I would say you have a lot of boys, so hopefully I am wrong and a better picture will help.

So far most of them quack. REALLY LOUDLY I might add lol. The quacking is so loud, it's hard to listen for boys. We tried singling out a few last night by trying to catch them and every one we followed quacked.

However we didnt get to follow all of them

Here is an updated photo of my Khaki Campbell ducks. They all still look the same. I think I may have lucked out with all girls
