ok, don't bash me if i installed the fan opposite of the way yours is.......
but i installed the little fan over one of the vent holes and put water in the wells and ran it about 5 days before i got my eggs. it is blowing down, but since i put it in the temp and humidity have been much more stable and i don't seem to have to add water as often. still add some every day(plus i added a sponge so that may help too). so, i am hoping this works better than the last hatch that 1 chick of 12 made it. i had tried the "dry" method, and i probably screwed it up myself, but i don't think i will try it again.
