Sexing Rouen Ducklings

[smgustaf]

I have 4 7-week old Rouen ducklings. One has definite female “quack” when ready to be put down but others do not. Should the “quack” be a pretty reliable factor to sex rouens at 7 weeks of age? I have a video HERE if that helps for visual purposes (no quacking in video). Also,HERE is a photo.

It is usually pretty reliable by this point. Just based on looks I would have guessed you have three drakes and one hen too.

Thank you. I can see the hen’s beak color is different. What else do you see?

Besides the bill, the really black, mostly solid feathers on top of the tail. Girls usually have lighter, two-toned feathers. In your picture I can’t see the girl’s tail though. I tried to watch for it in the video but it is really hard on my phone.
