Hi all. First post here. My son and I thought it would be fun to hatch out some eggs so we built a styrofoam cooler/incubator. I plugged it in last night (25w bulb) and it heated up so much the digital thermometer/humidity screen was black! Obviously wayyyyy too hot. Should I try to find a 15w bulb or start cutting vent holes in it? If vent holes, where should they be? Down at the bottom by the light or up in the lid? I thought I'd cut a number and then start plugging them up one by one to get the temp to hold at 101.5 degrees (still air incubator). Any other ideas?
