I use a Solid State Little Giant Circulated Air Incubator I bought from www.eggcartons.com. It worked great. I was also able to get an egg turner and a plastic liner. A turner is a must so you don’t have do deal with the hassle of turning eggs. The liner made cleaning the incubator very easy; it lasted longer than other Styrofoam incubators I have used in the past too. The staff was very helpful and answered all the questions I had, the incubator was shipped same day.
Good Luck!
