Dead chciks

Did the air vents get accidentally shut after you removed the first chicks?

Hello! I have successfully hatched 8 eggs and have happy healthy chicks. I just had 4 chicks hatch yesterday afternoon, I woke up this morning to this? What could have happened? The incubator had the same readings as the other chicks I hatched!! Please help

I don't know much about genetics when it comes to this kind of stuff, so somebody correct me if this doesn’t make much sense, but are all of your eggs that you hatched from the same hen? Have you hatched her eggs before? Maybe she has some sort of genetic problem that caused this too happen?
