Ok, I normally only use my genesis to incubate and use my other homemade bator to hatch in. So does the fan keep the water beads from building up on the glass? This is my first time hatching with a fan too. So it freaks me out that there's no water build up. Normally I have a lot of water on the windows and can still see in, but it helps me realize the humidity is up too. Reassuring I guess you could say. So the lack of water build up makes me feel like they won't have enough humidity. Granted I do have a hygrometer in there but it doesn't work I don't think. I mean I put more water in there and it goes down. It nearly dries out and it goes up. So I don't rely on that thing. I filled both water troughs yesterday when I set them to hatch. Removed the egg turner, put the eggs in the carton. All plugs are closed etc. So it should be set right?
