I have two olive egger eggs with pretty detached air cells - one is a single moving cell and the other appears to be a 'duplex'. Both eggs have what appear to be normally developing chicks. I have them in an egg turner so the large end is always up- any hope these will make it? I assume the chick will eventually get big enough to force the air cell(s) to stop moving, right? I'll keep an eye on the 'duplex' - this is day 12. Anything I can tell when I candle at lockdown to determine if the chick will pip into a 'no air' situation on that 'duplex' air bubble?
