Misting the lid works better as misting the eggs themselves can cause chicks to inhale the droplets & drown.P.S. If I've got pipped or zipping eggs at the time that I open the incubator, I also have a bottle of warm water on hand and spritz the open-but-not-hatched eggs with it to counteract any membrane drying effect from opening the bator. I don't know that it's necessary, but it feels like a reasonable precaution to me.![]()
