Yesterday I found this in one of the nestboxes among a few other eggs. I've never seen anything like it. It's the color and texture of eggshell, but it's pliable and rubbery. I cut into it thinking I might see yolk and white, but it was definitely not egg material inside. It looked like folds of thin-sliced turkey lunch meat. It smelled sort of stinky inside, but not rancid or like chicken poop. The outside didn't really have any smell at all. Is it possible a piece of her insides got into her egg tract somehow and got covered in shell material? I don't know which girl laid it (or pooped it?). Anyone ever seen anything like this? I don't know if there have already been BYC discussions of this sort of thing, since I"m not even sure what I'd search for. Thanks!
