Ok, most of my hatch pipped and were out of their eggs day 21. I had one late arrival on day 22. I was about to throw away the last remaining egg this morning but it was chirping and wiggling around. I thought for sure it was dead because it was chirping yesterday and had not pipped through out the night. My question is, do I just let it go and see if it pips? Or should I pip and help it out?
