When you put hatching eggs in the incubator before noon that is considered day one. If you set the eggs in the afternoons or evenings the next day is considered day one.
Yes you should turn the eggs today as day one. Your hand turning? So odd number of times a day. I turn 3 times when I hand turn.
I keep my humidity levels between 40 to 50% the first 18 days. 32 is not too terribly low but try to bring it closer to average. Everyone uses different humidity levels, what works for your hatch might not work with someone elses. my thoughts
