the hovabator we are using says that for lockdown, you fill both basins in the bottom with water, close up the incubator and don't open again till hatching. is that good enough, or do I need to put a humidity monitor inside? we are so freaked about all this... the stakes are high as the 7 yr old watches this unfold... if day 21 is Thursday, and we put them in to incubate in the evening, will they be likely to hatch in the evening, or will they start on day 20? super confused about how that all works. when they hatch, they stay in the hovabator until they are all fluffed up, right? is it ok for them to stay in there until all the babies are hatched and fluffed? because otherwise you're opening it up and letting out the humidity before the babes are all hatched. why is this so hard? why are we doing this? AAAAAA!
