Guys, something about his incubator doesn't make sense. In one of the threads he mentioned that his thermostat is set at 99 and the egg bins are at 88 and 90. That means the incubator isn't insulated well, and it is losing a lot of heat and humidity. I find that if you have a well insulated incubator, set the whole thing at 90, the bins will heat up to that point and then keep the humidity in the incubator high as well, which helps keep the egg bin humidity high. I keep my incubator above 70% and then the bins stay near 100% with the vermiculite.
