Rouen Confusion: Sex and Bills

So my flock of 8 is around 3 months old now. I've determined through voice sexing that 5 are female (2 fawn and white runners, 3 khaki campbells), 2 (1 rouen and 1 khaki campbell with a perfectly-developed drake rasp) are male. There's one rouen, though, that's just confusing me. He seems to be the "odd duck." Several of them are starting to molt their juvenile feathers, including my rouens. These rouens are from the same hatchery and are around the same age, but they look entirely different.

The one I'm absolutely certain is a male is the one on the left in the photo of both of them. He's got the dark head starting at the bill, and you can see his white ring beginning to come in. He's even got some tail feathers beginning to curl.

The other one, who has been absolutely silent since he stopped peeping and cheeping in the brooder, so I've been sure he's a male, looks incredibly different. He's got a substantially bigger/longer bill, it's a different color (I'm color blind, so I won't speculate). No sign of the white ring coming in, and his stance is entirely different than the confirmed drake. Anyone have any thoughts here? I've been certain they're both males, but neither one of them has a drake rasp yet (they both kind of squeak if you pick them up). Aside from the complete lack of voice, I have nothing else to go on with this duck. Second photo is of the duck in question.

Is it possible this duck is a female?

For me, a combination of...
lack of quacking
bill color
green sheen coloration on both of their face/heads
grey feather coloration near the thighs
Once you have raised ducks for a while it becomes very easy to differentiate the genders, it just takes time.
This is why I'm asking. The combination of being color blind and not knowing exactly what to look for makes knowing these things better than "It's a drake." 😉 It was super clear with the first one to me because he's developing so much faster than the other. He's hitting all the telltale drake milestones (white collar coming in, tail feathers curling, head turning super dark starting at the bill). But the different bill shape, color, lack of collar, etc, had me questioning the other, and also not having any confirmed female rouens to compare to (since both of my rouens lost the duck lottery) made it probably a bit tougher.

Unless it starts laying eggs, I'll just continue knowing that he's a drake.
 
Looking for help sexing these Rouens. I think I'm identifying 3 males and 1 female (based on bill color and head sheen) which I could be wrong about, but there are 2 that I'm REALLY not so sure about. I would say they are about 13ish week. No more than 15 weeks. Any guesses? What do you see?

Hello. I'm new to the site, so I apologize if this is in the wrong place. I'm wondering if anyone has had an all-black Rouen duckling? I have the parents. They are both Rouen, and up to this little jewel the ducklings have hatched looking as I had expected. But this one duckling is completely black. In the picture there appears to be a couple areas that look more grey, but that is an optical illusion. Or maybe the camera caught what my eyes did not. Lol. To me he's completely black with the exception of his lower bill, which is dark yellow. There are still a few more to hatch so I'm hoping for more. I love the look of him!!

But it's he Rouen? Or maybe he is mixed from somewhere before the parents? I'm confused and thrilled at the same time 🤣

Check out this thread! Someone else had an all black Rouen as well and shows what she looks like fully grown :)
