I've had my incubator up and running for 10 days now but the temperature keeps fluctuating. I don't know how to keep it stable. Does the room temperature need to stay in a certain range? I've had a spike up to 106 and a dip down to 96. When it is stable it is at 99-102. I'm new at this, so any info would be appreciated. My first batch is in the incubator now, but they are just test eggs from the grocery store.
