Duck Laid Weird Egg

Did you take pic of the blue-green spot?
Duck egg yolks change color when they are fertile?
@WVduckchick

Other than blood spots or normal occasional meat spots, I've never seen any other color inside my duck eggs.

What kind of ducks do you have @WVduckchick

 

[Phoenixheart14]

Black Swedish, but only drakes now, sold my girls. And I also have Call ducks.

I love call ducks!!!! What varieties?

My girls are silver, grey, and blue fawn. I had a silver drake that got snatched by a hawk last week, so my only drake now is a blue fawn.
I have 15 eggs in the incubator and the girls have started a couple nests. Whichever sits first gets to keep them
