First time hatcher here. Bought Miller Still Air incubator for around $45 at the local Southern States. Was using the tiny thermometer that came with it. Kept it right at 100 degrees. Then went out to buy a Walmart Hygrometer, plus thermometer.....the thermometer clearly doesn't work....wondering if the humidity measurement is any better. So, now not trusting that the first thermometer was right either, bought another larger thermometer at Walmart for $2 to try and get a correct reading...now I've got THREE different readings, all varying quite a bit!! Last night, trusting the Walmart one before I realized it was prob way off, my temp was probaby at 102-104......although I didn't know it til now because the readings seem to be about 4 degrees off. Which thermometer do I trust? Has anyone had any experience with the tiny little thermometer that comes with the incubator. Actually I think it might be the more accurate of the 3, but wondering what you all think. Have I ruined my eggs with all this flucutation? I guess overall I've been keeping them between 99-100, except for a short while that they shot up to 104-106 this morning...I caught it prob within an hour or less of that spike, and took the lid off immediately. I had no idea thermometers would very SO MUCH!! Help! And thanks for sharing your experience!! I keep reminding myself this is supposed to be FUN!! ha!
