To begin with, we finally got our first egg yesterday! The egg was a good size with normal shell hardness. This morning I went outside to let them out to run around the yard and I found something strange. It seemed to be the outside of an egg shell but it had the feel more like a deflated balloon. It wasn't a complete egg shell (if that's what it was)...it was torn down the middle. Is this something normal or should I be worried?
