Duck Laid Weird Egg

[Northern Appalachian]

One of my Khaki Campbells laid an egg with a blue-green spot in the yolk. They only just started laying again a few weeks ago, we washed and refrigerated. It was laid in February. Has mold set in already?

Is that the only egg you've noticed with the spots?

Yes

Sometimes in eggs there is a spot called a meat spot. It’s not inedible. You can eat it and be just fine. I’m not sure if they could be blue green tho.

Do you have a drake? Sometimes I get weird colored fertile spots in my duck eggs.

Yes we do have a drake! I was thinking that was it judging on the cyan coloring.

That's the culprit! I'm so glad it wasn't a medical issue.

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

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

I have Welsh Harlequin, Cayuga, and Blue and Black Swedish. I get fertile eggs from all of them, and a few times a year I get colored fertile spots from the Swedish. I'll defiantly post if I get another one!
