Unusual deposit on eggshell Opinions, Please?

Hey, those look like tiny undeveloped eggs!!! They don't look like calcium deposits to me.

But I'm not an avian reproductive engineer.

It's kind of a cool picture.

It's a fractal egg!

Those are the "clusters" I've been finding on one of our Cinnamon Queen's eggs this last week. It's almost like sand got wet and stuck to something, because I can just wipe them off with the pad of my finger without any damage to the shell itself. There were several clusters on each of her eggs though. I was very worried at first. So verdict is, it's just too much vitamin D? She is about a year and a half old.. certainly not a new layer.
