I had good luck with quail eggs. Not so with chukar partidge. I also have a seven egg incubator that has a temperature display. If yours is like mine, make sure the thermostat wire that stand up inside the bator does not touch the plastic dome. If the wire touches a condensed dome the reading will be inaccurate; the actual temperature will be much higher destroying the eggs inside. Other than that, my incubator keeps a very constant temperature and works well. It isn't possible, though, to regulate the humidity; at least, not very well.
