My incubator is a homemade one with a lightbulb. thermostat, and a PC fan. I have it set with eggs right now and it is staying at 98 to 101 degrees. I have a brand new thermometer right under the thermostat and it is reading the temperature accurately. Anyways, I put in the cord that is attached to a different themometer and it is reading a few degrees less. (I put it in the opposite corner relative to my thermostat. The end of the cord is inside a water wriggler just like everyone has suggested. My question is this: Is it alright for it to say that? Could it just be getting a different reading from the water wriggler? Thanks! Cody!!
