Abnormal growth inside egg: help identify the problem

[AdiShakti]

First time posting and joining- I usually find answers here without the need to post- but I have found something weird I can’t find anything else like it! This came from one of my smaller Sultan hens. Came from inside the egg. To me it looks like an underdeveloped eggshell inside the other egg. It’s hard but soft- seems hollow inside. Any clues would be helpful! Is this a sign of problems I should be aware of?

Welcome to BYC

It appears to be some oviduct tissue that split off and got captured in the egg.

It happens occasionally, and is of no worry unless it happens a lot. Then you've got egg duct inflammation or something going on.

Just watch. Usually you only see the occasional oddity like that.

What's inside that larger blob?
Cut it open lengthwise and take more pics.
How old is this bird?

Oh, and... Welcome to posting on BYC! @AdiShakti

Thank you! Great idea this is inside both the blobs- seems filled with same mucous type egg white substance. Feels like jelly. Bird is small sultan and a year old maybe year and a few months

Great pics.
Could be partially formed egg being encased in a fully formed egg,
or shed oviduct tissue as @Lady of McCamley mentioned,
or the beginnings of infection.
Only time will tell.
Hopefully it's a 'one off' and you'll never see it again.
