There are hot and cool spots in probably every bator . Even with the fans. The turner motor gives off heat. I know yours is made different but Im sure theres a motor there somewhere. LOL
Could be but I dont think so hun. I think it may have been off for a little while. Different places in the bator matter too. Did you move the eggs in different spots through incubation?
