I'm honestly not sure. I mean the running joke with Susan is that the only way to get it to work properly is if you stick it in a refrigerator while it's running. The problem with it is that since it's a home made incubator the heat source is two light bulbs and the fan that I tried to install is busted. Sooooooo while in December when I used it it stayed at around a stead 102 degrees as a still air, in the spring time it was fluxing all the way up to 106
It was my first incubator ever so I kinda just ran with it. It hatched out three beautiful Ameraucana babies in December (the first time I used it and the reason why I built it) so I'm not too upset with it. This past hatch was just bad.
