I spent the weekend with an empty LG on loan from a friend. She had really good success with it just following the inclosed instructions. I have been pouring over BYC hatching threads and cornering BYC hatch experts where they lurk to maximize my hatch which will include some very special shipped eggs from a couple of BYC ladies. I have been able to easily get it to maintain temps slightly above and below the 100 mark. Still working on getting right there but am wondering how big a deal it is if I don't I have 4 thermometers in there including a digital. My friend who loaned it to me just used the one that came with the bator which I don't think would show the 1/2 degree difference. Am I over teching myself?
