I don't know too much about chicken incubators and that, but I do know that you can make simple incubators out of cooler boxes or even styrofoam boxes, like the kinds shops get fish in. I'm not 100% sure how to make them (You'd need to find a tutorial!) but I am pretty sure you just have the styrofoam box, with heat mats and a thermostat, and then a cooling rack (like for baking) to keep the eggs off of the heat. Sorry I can't be of more help!
