it's still regulating, was up to 77% and now coming back down. We are at 61% right now. I won't be adding any water after this evaporates. Since they will create their own humidity as they hatch as long as the humidity is above 40% to start we should be good. Especially since days 1-18 were 18-25% humidity. I was reading some that said humidity 70-80 bu that jsut seemed to high for me, especially doing a dry hatch.
