after day 10 unplug both vents for proper ventilation.I have them in the egg turner small end down , then i lay the carefully in the lockdown incubator, should i keep them upright? I know my humidity has not steady for a few days now , i did however open both the vents and that did cause a lower humidity so i plugged one in and it leveled out should i keep both undone , last hatch i kept them both plugged in the whole time
