Feather sexing?! How?

[Lexbarlow]

Hi,

I've read many diff ways of sexing ducks but I'm confused, some of them are contradictory when I look at these 2.

Can anyone help with this please?
1 of them definitely quacks but can never tell which one as they only do it when snuggled up together.
Pics arent great, they knew I was upto something and wouldnt stay still, ratings

What kind of ducks are they? If they are a mixed breed it can be really hard to tell. The color of the feathers will only tell the gender in some types, usually those with laced or two-tone feathers like Khaki Campbells. Yours look too dark and do not seem to have the two-tone feathers of Khakis. The beak and feet color sometimes give clues, but again, not yours. So, you are going to have to go with voice sexing I am afraid. You can try posting a video of them making noise.
