I kept trying everything... I had so many containers of water in the bater that I could barely fit any eggs and still couldn't get my humdity up.... I decided to mimic mother nature and made a little hay nest inside the bater (this is my hatcher I'm talking about btw) so I laid out a clean prefold cloth diaper on the bottom and set some hay in there in a circle, like a nest and sprayed it down with warm water. I was not able to get above 60% before and now it is consistantly 80-90%. Thought I'd share! I also like the hay nest because I can slightly tilt the air cell up. Looking forward to some geese now. I believe I lost the first one because of humidity probs. It internally pipped and then died.
