What the heck is this?

[ThinMintTheChicken]

So my mom found this weird black-ish blob in one of our duck eggs. Duck is a khaki Campbell x Cayuga cross. Eggshell was thin and egg was smaller. From one of our younger layers. I'm so confused, does anyone know what it is???

Meat spot. I wouldn't eat the egg.

Oh gosh, of course not. Is it black because it's a Cayuga cross?

I would say so.

Okay, thank you for your help!
