I have a home-made cooler style incubator, I have water 1/8 inch deep on the bottom bowls on the rack and my hydrometer says the RH is only 48% .... It is so moist & wet in there, yet it still says 45%-48% ....I live in Florida and in my house with the AC on its 55%+ I am guessing the hydrometer is bad? It just doesn't seem right. Are my Duck eggs OK if the RH is way too high? HELP!!!! A BIG Thanks in Advance!
