What is this on my yolk??

Hi everyone,

So I have had chickens a long time. I've never seen something like this in one of my eggs. This egg is FRESH. Today's egg.

What the heck is this.

Almost looks like "mold" ... No clue but waiting to see what others suspect

I saw that with store bought eggs a few years back. I'm curious! Following.

That's what I thought too!
Is it really greenish or is that just the lighting in the picture?

This post from 2010 has something similar: https://www.backyardchickens.com/threads/green-spot-inside-egg.282921/
Here is one of the answers:

It is just a piece of tissue that sloughed off during the eggmaking process. Just pick it out like you might do with the blood spot on the egg on the left and cook it up.

I also found this in a post from 2012:

So, according to Storey's Guide to Raising Chickens:

blood spots usually appear in first eggs or in an older hen "indicating it is time to cull". Blood spots may be triggered by too little viatmin A in the diet or they may be hereditary."
Meat spots appear "brown, reddish brown, tan, gray or white usually on or near the yolk. Such a spot may have started out as a blood spot that changed color due to chemical reaction, or it may be a bit of reproductive tissue.

So I guess it might be a decolorized meat spot? We have a girl who frequently has meat spots in her eggs and once you look past the color is does kind of look like one.
