I'm on day 22 of my first hatch. Out of a dozen eggs, I have eight chicks, the last two of which hatched this morning. The four remaining eggs haven't pipped. I just candled them and they have HUGE air cells. I can't see any movement in the dark part. Do you think they're dead? I have my doubts about three of them especially because they were closest to the light bulb in the incubator. It was probably too much; I had removed the foil shield over the bulb because it was wreaking havoc on the temps. (Until lockdown I would rotate all the eggs when I turned them, so nobody would stay close to the bulb for too long.) The eight chickies are doing well.
