I've read your other replies about this and I understand your worry! It can be very nerve-wracking, truly! But I just wanted to point something out that you may not have thought of. Your chick pipped at the narrow end of the egg, so opposite the air cell, correct? The normal progression is pip internally --> pip externally --> unzip. It can be 48+ hours between internal pip and unzip. Well, the whole purpose of the internal pip is for the chick's lungs to start working. They break through into the air cell, the lungs start working, and the chick waits while the yolk sac is absorbed and all the veins lining the eggshell close off. Well, if your chick is backwards, there's no air cell to break into and they simply skip the internal pipping step and pip wherever they can, which is straight through the shell. The lungs need to start working one way or another! So often chicks that are backwards in the shell make their external pip way ahead of the other eggs. This doesn't mean they're ready to hatch yet, usually. It just means they skipped the internal step. They still need to wait many hours for all the developmental processes to finish before they are ready to unzip. So give the little guy time, don't rush in. Nearly all my backwards pippers make it out by themselves. I've only had to help a couple. So that little chick may surprise you yet!
