When I incubated last spring I was told to keep the temp at 100/101 F. 99.5 should be fine. The humidity helps keep the chicks from sticking to the shells when they hatch. That could be such a pain. You want to turn the eggs twice a day (I did every 12 hours). Don't do it by hand. Use an old egg carton, pointed side down. Tip it one way, then 12 hours later tip it the other way, and so on. Or you could get an automatic egg turner, then all you have to do is set them on day 18. Make sure you're home all day on day 21 so you don't miss anyone hatching! Try not to let it get too drafty in the incubator. I had to constantly watch the one I originally used because the temperature kept fluctuating. It was crazy. And when it gets closer to hatching day, the temp really goes up, so watch that thermometer CLOSE so it doesn't get too hot. Don't want roasted babies! Good luck, and happy hatching!
