I agree i think hovabotor is the way to go. I think you can get them for like $50 bucks. You have to watch the temps a little more but its worked fine for me. They say you can put a bunch in those incubators but i think you could only fit a few clutches. If you have the money to spend those would be fine. but hovabators are really just as good. You can also make a bigger one out of a broken mini fridge, and little flexwatt computer fans, and a thermostat, and it will hold hundreds of eggs.
