Sexing my ducklings

[tracykathryne]

I got these ducklings 6.5 weeks ago and am not sure how old they were when I got them but guess at least 1 week. I believe the Pekin is female because she quacks. So far I have not heard a quack from the other three, which I think are Rouen but could be Mallard. Before they got their feathers, one had a white ring around the neck so I thought that I might only have one male but now I can’t tell! Any guesses on their sex?
Here’s a photo just a few days ago and another from several weeks ago.
Thanks!

Looks like three drakes to me.

all the rouens are drakes, hopefully the pekin is too. all boys is the perfect flock (no girls to fight over, no egg issues like females have, etc)

Oh no I hope that’s not true! I got them specifically for eggs.

I’ve heard drakes don’t quack, but the pekin does. Is that not true?

what makes you say the doyens are drakes?

thank you!
