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,
Katherine

There are quite a few anomalous eggs out there, in fact there's a website devoted to them, which I've had recourse to visit before:

They do describe a phenomenon (though rare) where an egg can form within an egg, ovum in ovo.

According to one Douglas Russell, curator of the Natural History Museum egg collection, ovum in ova most likely happens because “....the normal rhythmic muscular action,
or peristalsis, that moves a developing egg down the oviduct
malfunctions in some way.” (via
