Okay I started gathering eggs on the 25th and and now I have enough to set I can't get the incubator to maintain even temperatures. I did buy 2 new digital thermometers but now my DH thinks that it's the thermostat going out but it has 2, and electric and a back up wafer thermostat. I say it's not maintaining temperatures because the weather decided to go all crazy and go from almost 70 degrees to 1 degree outside and it's in the insulated shop. There's no heat in the shop so I finally convinced him to let me bring it in the house, but I had to let him put this car he is re building back in the shop! (our compromise) So what do you guys think, it is the cold or the thermostat going out the makes the temps vary?
