Help! My son built an incubator out of a regular cooler and we turned everything on last night. It has been about 12 hours and the temperature is in the low 90's and the humidity has steadily dropped to about 39%. What do we need to do to fix this? It is a regular (not all styrofoam cooler), 40 watt light bulb, PC fan, has sponges with water in the bottom and vent holes are covered. We have chickie eggs coming this afternoon and don't know what to do now. Thanks so much.
