Hi, I'm going to be using my Octagon 20 Eco for the very first time. Where does the glass thermometer go?? It must be in the water, but it doesn't fit through the black grate that the eggs sit on. (Are you laughing at me yet?) Am I supposed to put a separate container of water in with the eggs in which to place the thermometer? Or should I pitch this glass thermometer anyway and just use the temp/humidity hygrometer from Wal-Mart? I'm confused! Thanks for your time.
