I'm so frustrated! No matter what I do the temps are going crazy in the incubator. I just received Crevecoeur eggs today, and I don't want to destroy them or be hovering every 5 minutes...like I am everyday this week...can someone tell me the name of the things I need to buy to build a regulator for the temp and fan please. I'll go out and buy the stuff today and my daughter knows how to hardwire things-I'm pretty handy at it too. Right now I have a fan, a little light/40 watt bulb, a large wide vat of water and hardware cloth the eggs are sitting on, all inside a large box lined with permanent foam molded to it. The temps were good until the humidity dropped outside-at least I think that's what's wrong. Thanks.
