I have an egg that piped yesterday afternoon, and now it's been 27+ hours with hardly any progress, it's just made the pip hole a bit bigger. The pip is closer to the pointy end of the egg too. I can hear it chirping and it wiggles & pushes the membrane by the pip (there is an air hole). I'm just wondering how much longer I should wait before checking on it closer? I have only 1 other egg that pipped this morning and it has a hole bigger that the first ones. None of the other eggs have an visible pips, and it's day 21. Thoughts, advice? Sorry for the terrible picture, my phone doesn't do well thought the incubator walls.
