My issue is humidity. I read many other threads but to be honest I find them controversial. Some say less humidity some say more? I've attempted this before in an older incubator. I started with 41 eggs and if not all than most were either hatched or piping but, my egg supplier told me to leave them and don't touch until all had hatched. This ended badly, the humidity was too high and all died....ughhhhh. I have started again with a newer incubator, genesis hova bator with LCD screen. My incubator is in my basement for the temp is nearly constant. When I fill up trough 1 humidity is high at about 65 with the vent pulled out. With the vent in its over 70. Tomorrow I will be starting lockdown, should I fill up trough 2 or just refill trough 1 and leave the plug in?
