Hello all, I am new to incubating eggs and have a question about my humidity. How do I keep it steady?!? My manual says I should only need to add water every 4 days but I am adding it every 4 hours to keep it steady!!! It will go up to 60 when I add water but then over night will drop to 5%. I have tried a sponge, adding water in the space in the bottom and even putting a little bottle open with water and nothing keeps it steady. Any ideas? Thanks!
