I made a homemade incubator because I am hooked like so many others. However I started wondering what is the best way to wire the fan. So that it turns on and off with the thermostat or not. I have it wired separate for now so it runs as long as it is plugged in, but I wasn't sure if wiring it along with the thermostat so it will turn off would be better or not. Does the air need to be circulating all the time? Any opinions are welcomed.
