I have no fan and my temp stays wonderfully regulated. I have no way to measure my humidity but I see it and spray my eggs when I turn them. I have the heating pad covered with a dog pee pad and plan on moistening during the hatch. The sponge in the bowl seems to be doing the trick. Wish me luck cuz it's either incubator or the raccoon gets. The raccoon will not go in the trap. The ducks sleep in the chicken coop now.
