Hi, I found a white little ball in an organic egg I had. The Egg was fine I just had to remove the ball. I was wondering if you knew what the white ball was? It almost had the texture of being a sack. we opened up and it had white mucus. It was the size of a grape.

Thank you,

or peristalsis, that moves a developing egg down the oviduct
malfunctions in some way.” (via
