Boys or girls? 8 week old Muscovy ducklings

[Seastar888]

Hello everyone!

I've been watching this forum for a while now, and I've finally registered after getting some ducks!
I'm very new to Muscovy ducks and ducks in general, although I have been sure to do plenty of research before getting these four.
I've had them for a few days now, and they're settling in really well. I always wanted to have one drake and three ducks, but at this age, it's still pretty hard for me to tell what I've got. The three white ones are about 8 weeks old, and the grey/black one is only 6-7 weeks old. What do you think they are? Any input is greatly appreciated!

This is a picture with all four of them together, just so you get an idea of body size in comparison to the other ones.
Just to make it easier for myself, I'm gonna call the grey, younger duckling duck-1, the very bottom duck, duck-2, the very top one duck-3, and the one with the slightly darker head 4.

Duck 2 on the right and duck 4 on the left.

The pure white tail is duck 2, the light brown tail is duck-4, and the duck you see is duck-3.


I'll have to take more pics, but hopefully this gives you a rough idea. I'm also curious to know if you can tell what colour they could be once they are fully mature?
I hope I haven't confused you all!
All I hope is that they aren't all boys! What are you looking at to tell what gender they are? Just so I know what to take pictures of!

Easiest and surest way is to voice sex them. Have their voices started to change?
A video of each making noise would help!

I go by foot size, leg thickness and body size more than anything else.

Thank you for your input! At the moment they just peep a bit, and the three white ones are definitely more quiet than the little one. Every now and again they do make a bit of a peeping noise. One of the ducks did make some hoarser almost quack-like noises today, although lower pitched and a lot quieter than other ducks. (I know that it's not quite a quack, as I have heard other duck breeds before.) Would that mean anything? It was the first time I had heard that. I'll try and catch any other sounds they make.
Thanks Kiwibird, as I said I'm a novice with ducks so I can't really tell whether one duck has really large feet (for example) or not, as I don't really know what the norm is! But I'm already learning a lot here!

They sure are cuties! Muscovy aren't voice sexed the same way as Mallard derived breeds, maybe @Miss Lydia @oldhenlikesdogs will know.

By 8 weeks a drake will be larger than any females of same age. By 10 you can really see the difference. Beautiful Muscovy, Carnucles will be more defined in a drake. Legs thicker set farther apart under neath the body. Longer from head to tail. Female have football shaped bodies shorter in length through body than drakes. All of this will be more noticeable in the next 3-4 weeks.

Thank you!

Also voice females will make a trilling noise drakes will huff. This is when they find their voices.

To me the white one's look like females currently. The one darker one may be a male, but give them all another few weeks.

What makes you think that? I'm just trying to wrap my head around all of these different methods to tell them apart. Thanks everyone!
