You can use a cool down cycle but is would be manual. The risk is forgetting to turn it back on. Some set an alarm on their smart phone to remind them. Others go to the incubator, turn it off and then go do the chicken Chores. After the chores are finished, they turn the incubator back on.
I have done this when hatching in the Genesis when the Brinsea is full. I only forgot to turn it back on once...The chicks were fine too.
Thank you... So...what is the purpose/advantage of the cool dow? Also- what are the lengths of time and intervals, when doing manually?
