Keep the faith... One of my incubators went down to 93 the one day because of a power outage. When the power came back on one of the incubators went up to 115. Another time on our coldest night We lost power, I was 2 weeks into incubation. The temp in the incubator was 78 degrees when I discovered it. I put the incubator on a battery pack with an inverter and brought the temp back up. I was really worried but I still had good hatches.
