Does anyone have any experiace with a hovabator? It's been 5 days and I can't get the temp on mine regulated. Last night it fluxuated between 100.9 and 90. Is there a trick to setting the temp or is it just not a good incubator. Mine is a still air with no fan. I do have an egg turner in it though. I've never done this before. I just set the eggs friday night when I though the temp was set.
