Odd egg

[PaigeReddan]

Can anyone tell me what i am looking at here? My americana is four yrs old and laying thinned shelled eggs. The rest of the flocks eggs are fine. Today i found this shelless egg fairly hard with what looks like the shell pealed to the side. I provide both crushed egg shells and oystershell to them all. Is this what happens in an older hen?
Thanks for any help on this!

That appears to be a lash egg.
It can be a symptom of later in life reproductive disorders.

Don't think it's a lash.
The bluish blob to the left looks to be a thin shell.
The egg covered in 'gunk'( that looks to be membrane and albumen).
Further dissection would give more clues.
I'm guessing a 'back up' of a shelled egg.
