Ok, so background...LG still air, auto turner...hatched out 3 of 3 fertilized eggs first time. They hatched Sept. 26th. Sept 28th, at 9am, set 30...a mix of 18 shipped eggs and 12 from my own flock. Candled day 6, marked the ones we thought had trouble, day 10, and got rid of 8. Day 16, got rid of 4 more that were questionable the last time, and showed no growth, leaving us with 18 viable and confirmed alive and moving on day 16. Lock down, day 19, was Sunday morning. We're now on day 22, which means 4 days in lock down. No pips, and I can't hear anything going on. Removed each one from the bator for a very, very quick inspection, two at a time (wife was helping), to look for pips and to hold up to ear to listen for anything. After putting them back, might have seen one move. Not seeing anything else. So...opinions? I don't think I had any low temp spikes that would have caused a late hatch. Might have had a few high temp ones, but very short lived and only to about 104. All 18 were viable just a few days ago. Where am I at here? I'm in no hurry to pitch them down the mountain or anything, but I am worrying. With so many different egg sources (5 different hens), shouldn't I be seeing something by now? Is the fact that nothing has happened a sign of some kind of event or issue that killed all of them? How long do let this go and seriously continue to hope that something can still happen?
