Your humidity is higher than I would be running it at...60 to 65% is adequate. Too high humidity will cause problems, 'stuck chicks', taking longer to hatch, which in my observations, leads to crooked toes.
No, I don't think it's a genetics issue. Theres a certain percentage of embryos that will stop developing/die in the early stages in incubation, another percent mid way through and another percentage at the end of the incubation period, that percentage varies with the amount of eggs set, I can't remember the exact percent off hand.
The ones that are just now pipping have been in an area of the incubator that wasn't at the correct temp, lower temp than 99.5°F.
I would let the ones that have pipped continue to hatch but after they hatch, I'd consider that the end of the hatch.
I see. Any way I can make sure the temp inside stay the same in different areas? I have a circulated air incubator but it is a styrofoam one.
In general, how many days do people typically let their hatch continue before calling it a hatch?
