Curious. I had one egg that the chick pipped in the middle, which seems to be the hardest area for them to break out of. He pipped maybe yesterday. He had a hole to the outside world, just hadn't finished the complete cracking until today. I came home from work to find the shell all around the middle of the egg gone (in a thin line) and the inner, leather shell attached but shredded, it was like spandex! I opened up the egg as I didn't hear anything and there was a fully formed chick, dead. I don't recall him chirping as much as the others yesterday. And he was fine earlier today. He was really stuffed in there. So I'm not sure if he had some sort of abnormality and he grew too big and just didn't have the room to push out or what. Anybody else have this problem?
