I just candled the chicken eggs which went through a nine hour power outage on day seven of incubation. Today is day thirteen and the first chance I have had to look at them. I have close to the same percentage as normal (80%) so it does not appear the eggs were affected. I allowed the eggs to rest (no turning) as the incubator temperature level normalized. This was more due to the extra work the outage caused. After the first 24 hours, I rotated as normal. In the past with power outages, we have lost eggs, so I was very pleased to see the "dancing dark blobs!"
If you have a loss of power, give the eggs a chance. A quail breeder acquaintance told me he had a power loss for three days and still had a few quail hatch.
