    I know humidity is important, but have you ever wondered how a hen can hatch eggs in a dry climate (low humidity) as well as in a high humidity climate like Tahiti, where it is like living in a sauna. Theoretically in Tahiti the eggs would never evaporate enough water to hatch, but they do. A dry environment is possibly more manageable as the hen may dampen herself down and then sit on the eggs, but how would a hen ever lower humidity?

    I agree completely. A hen can't control ambient temperature or humidity. She can only control the space under her and she doesn't have a de-humidifier.

    Good question, some say their eggs are less porous and in some areas they have more stuff in the soil that makes that happen too[​IMG] it is known that fowl take water in their beaks and put it in their nests though. Also I read in some abstracts that the clutch ph/composition is different to compensate. who knows, its amazing this world of ours.
