Has anyone out there used the temp/humidity thingy that hangs on a cord into the bator but registers outside? I'm getting a reading that the humidity is 10% but the temp is fine. I also installed a fan which is blowing right on it and maybe that's why the reading is so low? I now snaked the cord so it's laying on one side of bator on some eggs away from fan. Another register inside bator reads 42%. Anybody have this problem? there's only one hole to put it into on the hovabator. ? Thanx!
