Strange lump in egg

[girlsatwork]

Hi all, has anyone ever seen anything like this inside an egg? The egg looked absolutely normal, until I cracked it open. I found this strange lump, you can see blood vessels.
First egg she's laid after moult. No illness, that I'm aware of.

Looks like a lash egg that was contained within a normal egg. Happens sometimes at the beginning of a laying cycle.

Oh, thank you I have seen lash eggs before, but only ones that are rubbery and laid separately to egg, I didn't realise the lash egg could be inside another egg. This was very strange, especially with all the blood vessels. I've kept it and will dissect it in the morning.
I will keep a close eye on her. She's about 3 years old.

Would be good to cut that lump in half lengthwise.
I don't think it's a lash egg, which are not common or part on a new layers repertoire.
It might be an unformed/immature follicle.

Thank you. I've kept it, and will dissect it in the morning. I've no idea what an immature follicle is, will see if I can find some info

To me, it looks like it might be a large meat spot. Hens will occasionally shed little bits of tissue, and sometimes those pieces end up inside an egg. It would definitely be a good idea to dissect it regardless. I personally wouldn't be concerned, especially since she's just starting to lay after a break. The only time I would be concerned is if she starts showing signs of illness.

It's the place on the ovary where the yolks develop.
I think it's explained in this excellent video, which is worth watching regardless:
