yeah from your fridge! well she will hold a perfect steady temp! try taping all but one of the big holes on top, it will help hold humidity and temp, thats what i do.once you get it perfectly stable, TAPE the turny knobe thing down or something so you dont bump it or someone doesnt mess with it, its happend to me before, i told my DF that we wanted to use the brown cooler for another bator and he gave me the stink eye, so i laughed and told him we got a cool see threw mini fridge that we can transform instead and he thought that was neat. anyway, look i posted a pic of my cuckoos !
