The whole point of this is to see if it can work! I've had 90 percent plus hatchability with this thing not using it per factory directions. I want to see if the poor optimistic chick hatchers who buy this thing blind have any hope of success. I like the turner (mostly) and the heat has been very consistent, cleaning is a breeze, but the humidity is ridiculous, so what happens when a neophyte incubator wants to buy it for their kids and pops in eggs per package directions and disaster ensues? I know this is ridiculous and in theory won't work, but what happens in practice? And can I use that knowledge to help others better understand and succeed in their own endeavors. I'm also a hopeless geek, I have to understand things, know why and how. We're on Day 7, air cells are ridiculously tiny, humidity is consistently 80 percent. 2/6 were infertile so we have 4 eggs that seem to be developing normally. My guess is they internally pip (or try to) and that's it, but we'll see what happens!
