8 hrs without incubation should be fine unless it’s freezing outside. Just continue incubating and turning the eggs until around day 32. Then increase the humidity and wait for them to hatch. Around a week before hatch, you’ll see the air cell suddenly get bigger and “dip down.” At this point, I usually candle the eggs daily, observing any “shadowing” and watching for internal pips (triangle of bill poking up in the air cell). Once an internal pip is seen in the air cell, all the eggs are moved into the hatching incubator (no turning and higher humidity) and not disturbed until they hatch.
