So whats the deal with fans?

OK Why fans in an incubator? is it just to circulate the air? would a vent work as well or is a fan preferred? if so i was going to wire it on a timer

fans actually circulate the warm air so there are not any hot spots in the incubator. this makes sure all eggs are getting the same amount of heat. a vent would allow temperatures to fluctuate, so i think a fan is preferred.

ok so it would be stupid to set it up on a timer then it would be better to just keep it on

As long as your incubator is running, so should your fan.

i added two fans in mine one towards the bottom and one at the top. both on different sides so it creates a circular motion.
