I am going to attempt breeding next season, so I will be checking out incubators, or making my own soon. My question to the experienced breeders, what do you do when there is a power outage? Where I live, power outages are very common and I would have to have some kind of back up battery or generator hooked up to the incubator, I'm assuming. What are some things you guys and gals do to prevent temp changes in a power outage?
