sexing black swedish ducks by bill colors?

[microsat]

Can we sex black swedish ducks by their bill colors?

For example, the bill of black swedish drakes is orange by six weeks of age, females' bills are normally dark (black, or dull green).
In rare cases, drakes' bills are dark too. But none of females' bills are orange.

I had black Swedish a few years back. I don't remember being able to tell them apart, except for that all important drake feather!

From what I can gather.... And I'm brand new to Black Swedish ducks and mine are only about a week old or so I'm not 100% sure. But it looks like when they feather out that the drake has the curled "drake" tail feather as well as a green sheen to the feathers on his head, not as prominent as a mallard but noticeable. Where as the female is solid black and doesn't have the "drake" tail feather. Like I said I'm band spankin' new to Black Swedish, (or any ducks for that matter) and they're only a week old or so. I may be mistaken. Maybe a veteran duck owner will comment and set us all straight. lol

I have a female black Swede and she is green sort of iridescent in the light.

Is she green all over and a little more on the head?
