I have a Hovabator too, and it works really well other than the last 3 days. Holds humidity perfectly.
The older one I borrowed keeps temperatures better than the Genesis 1588![]()
I have two hovabators, one has the turner, when they go to lockdown I place them in the non turner incubator that is at the same temperature as the 1st. Seems to work great the last two hatches.
I have a Genesis 1588 with turners. I've never had any trouble with it loosing temp. The last time I hatched out chicks I had a 90%+ hatch rate. My biggest issued it maintaining the humidity. I have a hard time getting it to stay around 50% it normally goes way higher than I want it and I only fill up one of the water troughs. I need to invest in a better hygrometer because the two I have always read a different number.
