Gross! What is in this unfertilized egg??!!?

I think she and her recently euthanized sister have “reproductive problems” in that they each had wrinkled eggs.

I don't see it or your other thread.. maybe link it here?? Wait I found one..

So I wonder if that discoloration is still a yolk but infected with something like salmonella or other bacteria??

Alternatively.. possibly still a meat spot.. but a tumor that sloughed off?

This is a good article, # 12 and 13 address wrinkled eggshells..

Was this an egg from your hen recently, are the eggs since then had any issues?

She had laid it within the last 2 weeks. No issues before then, and I'm not aware of any since....but I use them as they lay them, first in, first out, you know.... It's a cyst of some sort, maybe an infection of something walled off in a cyst--maybe something like a fecalith, I don't know. I'll be cracking her eggs in a separate bowl before using them in the future, however, and I won't be giving them to neighbors and friends! Yuck.

This is from a hen about 2.5 years old, good layer, she is eating chick food right now with supplemental calcium available to her if she wants it due to new babies in the flock. This hit the pan like a rock. It’s vascular. No, I haven’t cut it open and don’t really want to! I think she and her recently euthanized sister have “reproductive problems” in that they each had wrinkled eggs. They recently euthanized one stopped laying for a long time and finally took ill. They are both splash marans and bought from a feed store as day-old chicks.

It is an intact Follicle. They do have veins around them.
Take a look at this thread particularly Post#4 that I made. https://www.backyardchickens.com/th...english-game-bantam-hen.1321148/post-21541961

Here's a larger intact follicle. Cool Huh?

Whole video is interesting, but follicles are shown at around 1:50

That's why I candle eggs I sell. Too many weird things.

Wyorp seems to have come up with the answer! So interesting, thanks for sending me that video, I watched it a couple of times. Fingers crossed I won’t see that again. Many thanks!
