Thing is, I raised Swedish in the past, and these don't have the body type to be swedish, but I think they all might be mixed. I thought cayuga also, but one of the all black ones is very much runner in shape and stance..... I think i need to take more pics, this one is a bit blurry.
Also, are not Cayugas shiny green? These are pretty much matte black.
I agree - when I got them I expected to have some hatchery stock layers, but did not expect mixes, I have never gotten mixed ducks from a hatchery before. So thats why I wanted you all's opinions.
Oh, also - based on the type of duck, medium size, when should I expect them to start laying? They are about 3 months old now.
