Well, I am just sick. I had a chick hatching just a few minutes ago. It was zipping and working it's way around the egg and chirping. I was doing other things and kept coming back to watch. I left it too long and came back and realized it was no longer moving. I grabbed it out and peeled it back and it had already suffocated and died! I'm sooooo upset! It was a BLACK which I really, really wanted. It was one of my own chicks, and it had perfect feet, too. In fact, the extra toes on each foot had amazing separation. I know, I'm sick, I popped it out of the shell, tried to rub it to stimulate it and then when I realized it was gone, checked it over. The membrane was stuck on it. It must have sealed up and suffocated it. I wish I had caught it sooner. No blood, no nothing, just slid right out when I peeled it back.
