open vent hokes after 3? Days.
No touch candle betwen day 11 to 14
Lockdown on day 21? Correct? Chicks day 28 +/-

I feel bad I think I had one more in a deep sleep trying to hatvh from last batch

hadn't emerged going on days

Chicken egg lockdown is day 18. Hatch is day 21.
110 F for more than a couple hours will kill the embryos. Continuous temperatures above 105, no embryos should be expected to survive.

Vents should likely be closed the first week as higher CO2 can benefit them. After that, vents should be open since the embryos need oxygen.
