Sexing ducks by bill color?

[Germangirlygirl]

I got 4 ducks in march, I believe them to be Rouen. 3 of them the beaks are a greenish color and one a yelowish color. I guess that means I have three boys and one girl. What should I do?

The female will have a loud strong more normal quack and the male will have a quiet raspy frog croak kind of quack.
The female ducks will have either black bills or black and yellow bills. My blue runner girl has a black and dark green bill.
Males will have a yellowish olive color bill.

What should you do?: Get 5 more girls or get rid of two boys when you can really tell.

I tried to get another girl and it turned out to be another boy.
Now I have 4 boys and one girl.
Is their anyone interested in some boy ducks? lol
How would I go about selling the boys? or even trading?

Listen to the audio on this link to determine sex by voice. We thought our boys were quacking until we heard this:

females are loud and males quack very quietly.

To add to this

The ducks make a sound that sounds like Uht, Uht, Uht where the drakes make a sound more like whistling.
