I was just checking my incubation info, as well as causes to problems and such. I have a lot of problem with eggs hatching 2-3 days early. I have tried adding a fan, lowering the temps, almost everything to keep this from happening. The info that I have stored in my bookmarks (3 different sites) all say humidity should be at least 50% for the first 18 days. It also said that early hatches could be caused from low humidity? I am no longer going to keep my humidity so low. How many people actually use this successfully?
