I ordered a used LG. fabricated a plywood patch for the missing window. She is holding temp like a champ. My prob is that i put too much water in and now it has been hollding 68-72 percent humidity. I have pennies over the vent holes and have made tiny adjustments because I would rather worry about temp. I live in the desert and am confident that the humidity will come down. I just brought eggs in and am going to let them achieve room temp prior to placing them in the bator. It is just another thing to worry about.
