What's your location. Until day 18 I think most people stress about humidity waaay too much. That being said location is key. In Oklahoma where I live I don't even look at humidity until day 18. I suspect that somewhere like Arizona would require a closer eye. As far as turning, I start turning after 24 hours for chickens but as someone said above you don't have to start turning for 3 or 4 days.
Scare tactics run rampant, and don't always get disputed. many things go on being believed, just because so-and-so said so!
