I turned it on today and the temp. has flucuated between 88 and 110 degrees farenheit. I have never owned a Little Giant incubator (only hovabators) and haven't incubated in almost four years. Also, I have a digital thermometer (that I got four years ago and used for my last hatch and has since been used outdoors.) I replaced the batteries and put that in the 'bator, and the Little Giant also came with a little mercury thermometer. So I put that in the incubator too. They differ by TEN DEGREES! The mercury one says it's about ten degrees hotter in there than the digital one. Which one should I believe?! As I said, the digital one proved to be accurate four years ago with the last hatch, but it has had the probe outdoors since then....So would that cause it to be less accurate?? Also, how much water to add to the L.G? It isn't really specific in the directions. I also took one of the red pluggs out of the top to release excess humidity. If you've operated a L.G 9200 before please comment! UPDATE: I have the incubator set up in the corner of my bedroom. It's about 67 degrees in there. I put my science project board in front of the 'bator to block andy drafts. The temp hasn't stablelized yet. Ranging fron 94 degrees to 106 degrees according to the old digital thermometer. How many of the water trays am I supposed to fill (I think there's three in the bottom of the 'bator.) Also, are water wigglers are those squeezable plastic toys filled with water that kids play with? My sisters play with those. We may have some in house. So does putting a thermometer in one simulate the exact temp it is inside the eggs in the incubator?
