My wife sells Tupperware. Normally not the first container you would use out of the cabinet for incubating eggs. They have a newer one though called a fridgesmart and it has these little toggles that open on the side to control moisture on your food. These little "flaps" also work AMAZING for controlling humidity for your eggs. There are little ridges on the bottom that keep your eggs in nice neat rows too. I used them this season and had 100% hatch rates on all but one of 7 clutches (lost 1). I just added the perlite and water, opened 1 of the "flaps", and let them incubate. I did bearded dragon eggs with it this time, but can't see any reason why they wouldn't work just as well for others animals. Check em out.
