I'm going to set my eggs tomorrow. I will be setting between 35-38 and due to the weather I'm not sure what to expect on fertility. My incubator is assembled and I had two quick things to tie up. 1) My incubator fired up, warmed up to 99.5 degrees in about 30 minutes. Should I leave it running until I set my eggs tomorrow or is it okay to turn it off until then? and if you have a HovaBator 1588 Genesis... 2) Do you fill up both water reservoirs or just the one in the middle? How often on average do you need to refill the water? (sort of hard to see with eggs/turner over the top) Thanks again.
