Strange thing found in duck egg

[Urban Waddler]

I have two female Pekin ducks and today when cracking one of their eggs, I found a nasty thing. From afar it almost looked like an embryo, but there are no male ducks around. Then I looked closed and I don’t know what the heck it is, but also noticed the yolk looked funny on one side. Whitebeard, my larger female has laid some interesting eggs. She started laying about a month ago. She laid soft eggs, giant double yolk eggs, and finally she started laying normal eggs. Now this. I just need to know if she is sick or what the heck this is?

@casportpony ?
I think sometimes they can get a bit of their insides (for lack of better term) inside the egg.
Reproductive track I think is what I'm trying to say. .but I don't know if this is a sign of issues to worry about or not.

It's called a meat egg. Could be laminated albumen that has been produced around the yolk or could be other material that has been shed from the magnum of the oviduct or shell gland.
It happens occasionally, also blood spots can occur when the follicle vessels rupture as the ovum is being released. Foreign material can also enter the oviduct and enter the vagina and be incorporated into the egg.

Thank you very much for the detailed response. I’m assuming you do not believe I should be worried about this? Thanks so much again.

Thank you sean!
Much better than my attempt at an explanation
