I put in eggs on Nov 1st and they were due Monday, but I only had one chick pip (on day 20) and it never zipped and died in the egg. Today is day 23 and I still don't have any other external pips, but last night one chick was peeping. No peeping at all this morning, though. I'm keeping humidity in the mid 70's, but for whatever reason my incubator went out of whack right after lockdown and is reading a 10 degree difference from one side to the other. I thought maybe all the chicks had gotten too hot and died, but on the cooler side 4 are still moving (I candled since it's day 23 and I thought they were all probably just dead) and the temperature is fluctuating between 95-100. Will the chicks on the cool side just hatch really late? My other question is this: I've been hearing peeping the last couple days but it goes on for a few hours then stops, and there isn't an external pip following it. Are my chicks pipping internally then suffocating before they pip externally? If so, what causes this? And how likely is it that they're internally pipping then just hanging out in the egg for 24+ hours silently?
