I just got new Brinsea Mini Advanced incubator this year to use in my room. I am very execited and planning on setting my eggs tomorrow. I'm taking advantage of the auto-stop turning feature (as it will be weekend when it's time to stop turning the eggs). I know that the first day you set the eggs does not count as the first of 21 days of incubation. Do I still set the Mini for 21 days, or for 22 days? Thanks!
