Sex of my Muscovy ducks?

[Going Quackers]

We have the opposite problem here, most black, blues and what, even our chocolate ducks didnt stay chocolate for long now they are more of a blue fawn / pale lavender feathers.

I am inundated with blues and chocolates here lol I do have whites, one black female... and then that odd blue/chocolate which everyone says is a lilac. I finally got a chocolate drake with my last hatch of the season, that was a shock. I have 1 blue drake and the rest whites or black & whites in various tones.

I need to add some different lines and colors but only want females i am draked to the max.
