My not so white Pekin ducks...

[mahsmaj]

Can anyone tell me how to tell if my ducks are male or female???

the two I can see the tails on look like girls, the male will have a curl by the end of his tail.
they also quack really soft if they are males, and very loud for females!

The females have a louder and sharper quack. It's especially obvious when you pick them up...the females will quack loudly and carry on and the male will have a much softer/quieter sound. The males also get the curly feather on their tail but for some reason I am often not very good at picking up on that.

I'd say the two are girls. Don't see the curl. Like the others said, females are loud. I was suprised how much louder they are when I got my two.
