My eggs are hatching and so far all chicks look really good except for one that has egg still stuck on it's back. I have an egg that pip fine then when it came time for it to zip it started then stopped it has done this since yesterday evening, (Thursday) at 6:00. what do i do the baby is chirping so I know that it is alive, it has only zipped one quarter of the way around the egg, should I carefully get it out or should I continue to wait and see?
