I got a free LG 9200 still air incubator. I have a Brinsea Octagon but the amount of eggs that I wanted to hatch simply didn't fit into the Octagon. Then a very nice person told me I could have her incubator, because she didn't want to hatch anymore. I got the incubator, read all about it and learned that it was difficult to use/regulate but there were some tricks to it. Three days into playing with it (without eggs or water and I also removed the turner because I wanted to hand turn to give the eggs a better opportunity to move about the bottom and get equal exposure to warm/cool areas) I got the bottom temperature to fluctuate between about 99.2 and 100.8, which, from what I read, seems to be the ticket. I had this same temperature in my water wiggler, on the bottom grate, too. It was very stable. Then I decided to put eggs in. I also filled up the small trough in the bottom with water as the humidity in there was 10% without water. I read to not adjust the temperatures (unless they went high) the first 12 hours. I got up every 1-2 hours and looked at the temperatures. I had 4 thermometers in there (one in the wiggler) that all seemed to basically agree on the temperature (with normal allowance for differences in position). The temperature(s) went down as expected and then came back up to about 95. And stayed. 12 hours later, still between approximately 95 (in the wiggler) to 98 on the bottom of the incubator. I even got out another temperature probe that we have for cooking and a really old mercury thermometer. They agreed it was about 95 to 98 in there. Early this morning (about 11 hours after starting incubation) I removed the eggs from the LG (at this point I still have room in the Octagon, the last shipment of eggs was delayed and should be here today) into the Octagon. The Octagon recovered to 99 within about an hour. Is this incubator possessed? Is this normal for still air LG? Why would it have been fine and stable and then not? Did I not wait long enough for the temps to come back up? I've read through a ton of information about this incubator and don't see this particular problem. Thank you for your assistance.
