I have a little giant incubator with the automatic egg turner thing in it. I am trying to get it to 99.5-100.0 as per what everyone here says. But I am not winning this battle. I have the little red things in the top, I put 2 thermometers in there because I thought the first one was messed up, but they both read the same. It started off at 86, so I turned the knob towards increase temp. Then it went to 105.6 so then I obviously turned it down, just a little and it dropped to 98 (after 2 hours) then I barely turned it up and it went to 102. I have been going up and down for 14 hours now trying to get it to 99.5 - 100 but I am not winning, no matter how little I turn that knob I cannot get it to get in that range. Do you think the incubator is bad? It is a still air incubator, and it is holding humidity at 63% for about 9 hours. I ordered one of the nice top brower models, but it hasn't come in yet.. And no, there are no eggs in it. Thank god, because I wouldn't want them getting a taste of the 4 seasons already.
