I get home from work at 5:30 an the power is out , Temps in the 88 and humidty is saying 90 , I run around looking for a heat source I end up with tea lights ,I watch my temps for about an hour til power comes on ! Now all is well Tomorrow is suppose to be hatch day hopefully this doesnt mess up my hatch !
This should make you feel better - from here

"Zone of hatching potential (35 - 40.5°C/104.9 - 84.5°F)
Within a range of 35 to 40.5°C (84.5 - 104.9°F) there is the possibility of eggs hatching. The
optimum (for hens) is 37.8 °C (100.4°F), above this temperature as well as a reduced hatch
there will be an increase in the number of crippled and deformed chicks. Above 40.5 °C
(104.9°F) no embryos will survive.
Continuous temperatures within this range but below optimum retard development and
increase mortalities. However it is again evident that early embryos are more susceptible to
continuous slightly low temperatures than older embryos. Indeed, from 16 days on it may be
beneficial to lower the incubation temperature by up to 2°C (3.6°F). I emphasis the word
‘continuous’ because the effects of short term reduction in temperature are different and are
discussed later.... If power loss occurs when the eggs are near hatching, incubator temperature is less
critical, but severe chilling will cause mortalities.....Remember that incubator thermometer readings will not be the same as embryo temperatures
when cooling or heating occurs. The eggs will lag behind the air temperature."
