What is this?????

I found this in 1 of my eggs this morning as I was making breakfast!!! Can someone please tell me what it is, I've never seen anything like this before. I collect my eggs from my ducks daily. It felt sorta hard & rubbery. Yes, it grossed me out!!!!!

Looks like some soft eggshell material, there may have been a disturbance when she was forming the egg which can cause funky stuff to happen.

I have actually seen that one time in one of my ducks when she was a new layer. Never seen it since though.
