Can not figure out my ducklings’ genders for the life of me!!! Please help!

[Sarahannedp]

Hey everyone! This is my very first post on here, and it is out of desperation. I have what I have been told to be one Muscovy, a black Swedish, a Rouen, and a crested Rouen. They are all about 10-11 weeks at the moment I believe. Though compared to other posts I’ve read they seem underdeveloped do their ages (pls tell me if anyone agrees/disagrees)- I cannot figure out their genders, no matter how many articles I sit here and try to study. Buttercup (the all dark brown one) and peaches (the black Swedish) both quack very loudly. Scooter (crested) kind of peeps but does quack sometimes I have noticed. Quavo (muscovy) was actually an abandoned duck that was found and given to me. I refer to quavo as a boy but that’s just out of assumption and has no association with what quavo actually is. He makes no sound at all, except sometimes he chirps. He loves to be held only by me and is quite attached to me but also gets along well with the other ducks. However he is dramatically smaller in size than the rest of them.
I would appreciate ANY help at all with figuring out their genders.
Thanks!

Ducklings can't be sexed this young except by vent sexing.

For the 3 non-Muscovy ones, do they quack loudly or do they have a quieter raspy voice? Female ducks are loud, drakes much quieter. Muscovies are harder to tell. S/he may alse be a mule (Muscovy hybrid) and I have no experience with those.

Sorry I don't know much about ducks - someone on the Duck Forum may be able to help you.

For the muscovy, if you can take a good pic of the legs @Nyla or @Miss Lydia can probably help. Males have thicker legs, but you might need to put your hand in the shot near it for a comparison.
They are all very cute!
We also have a duck forum here where you get lots of good info from other duck owners.

First Off Welcome to BYC! Glad another duck owner is helping take of BYC to make it BYD!!
The two on the left look to be Muscovy mixes.
More pictures would be able to aid.

I’m sorry, like I said this is my FIRST post and I clicked the first relevant thread-category that I saw. Thank you to those who have attached the link to the duck threads, and to the others who have shared their insight as well
