I have a Farm innovator still air, hand turn incubator. My last hatch shipped eggs I had 8/10, and this one I have not counted totals (local eggs), but it looks like it will be a good one. They do seem to be hatching on the 22 day not counting the set day. I have inside thermometers and try to keep it at 102 inside (good for still air) but the outside digital reading on incubator will be 99.5 which is fine. My humidity, i had at 50%, I kept the plugs out whole hatch on my last batches no extra liquids in the eggs, some one suggested that, I have more eggs coming later in the week I am going to try as Sally Sunshine says and leave in plugs until day 10. I want to do all I can for my last batch coming up, I have some neat eggs coming, one will be mauve, maybe gray, and a green one with white spots.
