I am very new to this site and to human assisted chicken hatching. One of the things that surprised me was the obsession with humidity. I was thinking there are some pretty whacky people here . Before I got my first batch of "proof of concept" eggs I decided to get a Meade TM005X-M Wireless Indoor/Outdoor Thermo Hygrometer. The bator was warmed, I drove 50 miles to get some fresh fertile eggs and joined the circus. WIth the auto turner I dont have to open the bator at all till I candle on day 10. I now have a remote sensor with min and max humidity and temp alongside my bed. I have joined the whack and depraved.
