Question: I have a Styrofoam cooler that has 2.5 inch thick walls, top and bottom I am thinking on making an incubator out of it because I feel it will hold temperature better. I am planning on using a stc-1000 thermostat and was wondering what type and watt bulb should I use with it I will also install a PC fan motor for forced air . It is a cooler design to keep insulin refrigerated while in transit so I feel it will do a good job holding heat. I am not going to put a window in it do not want to break the integrity of it holding heat but do need to know about holes for air intake and air exit so the eggs can breathe. I will have elevated pan in it for humidity this will allow for more eggs. It is still in design mode. It will hold between 10 eggs or so. Any suggestions on design would be welcome, it is about 14 to 15 inches square in shape.
