I can't get the darn humidity above 49%. I do not have eggs in there right now. The plan is to use it as my hatcher. I'm not having trouble with temps--they're staying pretty steady, despite fluctuations in room temp. But the humidity! I have all trays filled with water, plus three LARGE terrycloth rags spread across the floor and saturated with hot water. Plus the cardboard egg cartons I put where the eggs will go have gotten wet too. And the humidity is a rotten 49% I don't have any trouble with humidity in my hovabator, and it has circulating air. What is the deal? Help??
