For what its worth, I've used the Styrofoam circulated air hova bators and had good hatch rates. After they've hatched, it's more about keeping them from killing each and healthy. My local feed store incubates eggs for those who want them with out the hassle. I find it enjoyable when I do it myself. Cabinets are nice. I'd like to say, don't let it eat ya up, it happens, just takes a little practice.
