    So do not count the day I put them in the incubator ? Is day 2 really day 1?

    Correct. On day 2 the eggs have been in the bator for 24 hours = 1 day.

    Lol yes. Correct. You start counting 24 hours after set. Chicken eggs need 21 days of INCUBATION. So an egg doesn't have one day of incubation until it's been incubated for 24 hours. Then it's day one. So if you set at 1pm on Monday, day one is 1pm Tuesday, day two Wednesday and so on. If you set eggs on Monday, expected hatch (with ideal/accurate temps) would be Monday three weeks later. Expected hatch day is same day of the week as the set day. Hope that wasn't confusing.
    It's one of the things that is often confused in hatching.

    By day 21 you usually see pipping/hatching. You should at least hear some internal pipping. If you don't see any pipping by the end of day 21, I'd candle and see if they are internally pipping. But I can't stand not knowing what is going on, so that's why I am hands on after all...lol
    I'd double check the accuracy of your thermometers, your humidity results on air cells and shoot for at least a half degree higher.
