Hi I'm Shawn and I have never hatched a single egg. But I'm in the final stages of my diy incubator I can see how addictive this is I have every thermometer I can find sticking out of or inside a foam box and I check them all the time my wife thinks I'm loosing my mind can't wait till I set eggs. May need a coop big for me and incubator!! If test runs work out and grandfather's hens lend a hand I will set Saturday.
