Green spot on raw duck egg yolk

[Apolinne]

Good day friends!

Question: Anybody know what the hell this is ? (Pictures attached)
I have some Indian Runner girlies. They are a little over a year old. This was in one of their eggs today. It's like greyish green. The egg is at best 3 days old and was refrigerated the whole time. I'm not gonna eat it or anything. I just want to know if it means any of the ducks is sick somehow and if I should get them help. They all seem completely normal and happy. One of them lays a soft shell egg from time to time even with supplemental calcium. I'm not sure if it's anything to do with anything, but I thought I best mention it.

Thank you.

Fine normal happens sometimes when the yolk is forming and going through the reproductive system, a little piece of flesh or something gets in there called a meat spot you can actually eat it, but I never do I give it to my dog or my chickens

Aren't meat spots red/brown and hard ? like squishy ? I've seen a meat spot in chicken eggs before, it was literally like a bit of flesh. This was green and like, swirly, I thought it was like a green liquid, or like dust suspended in liquid. Freaked me out.
