So 3 of my chickens have hatched this morning (day 22) and there are still 10 eggs that have yet to hatch. They are pretty much all fluffy at this point. I am going to leave them in there over night to give the other ones a chance, but at what point should I open the incubator and let them out? And when should i candle and tap the other eggs? I am so scared to open the incubator at the wrong time, in case they have potentially rolled over an egg and i cant see the pip!
