Ugh, I am just bewildered and lost. I've been fighting thermometers for 3 days now. I've got 5 thermometers in the incubator alongside the digital one on the incubator. After readings all over the place on all the thermometers I awoke today to find all 5 backups read 96 or lower. Throughout the day I continued to bump up the temp on the incubator to try and get the thermometers to get up to 99.5 until finally I bumped it from 103 to 105 on the incubator setting. After an hour, still no change in any of the thermometers inside. With the incubator blinking crazily at me to turn the temp down I finally pulled out the three bulb thermometers. I turned one rightside up, instead of flat on its side, and left it in the bator and then checked the other two with a glass of ice water. The two I took out were both stuck at 94 degrees until I shook them and stuck them in water. The one I put vertical quickly rose to 104 degrees. I guess they all stuck from being on their sides????? Not sure how all of them could do that at the same time. So I reduced my incubator temp to 99.5 and low and behold the temp on the bulb thermometer inside came down. Fittingly, the two other digital thermometers I had in the bator never changed from 95 degrees during the entire day of fiddling with the temp. It appears that the incubator was right all along yet somehow 5 other thermometers were wrong. I am utterly baffled. Question is, are my ducks inside dead from being at 102 degrees or higher for the last 14 hours??? I have one batch on day 8 and one batch that I just put in this morning inside the incubator.
