I think my incubator must have cold spots or something. I can move my accurate thermometer around and get a different reading. I have the thermostat set to the right temp( that I figured out before setting the eggs) and the eggs feel warm like they should. Maybe it's just time to get a new thermometer. After the spike I had yesterday I just really don't know what to do. These eggs are only on day 3 so hopefully they will be ok. I might take the helpful hint about insulating around the outside of the bator. I just don't know, these are eggs from my own flock so no money lost, I just hate to see them go to waste.
