I have two rare breed chicken eggs in my incubator. I started with five but only these two have made it so far. They are shipped eggs, and have about 9 days left until hatch. Because of them being shipped, they have pretty significant saddle shaped air cells, and from what I have read there is really no way to fix that issue. My bigger concern is that when I candle them I can see fluid moving around in the air cell. What causes this and how can I diminish this? Reduce humidity? I am worried the chicks would pip internally and drown. Any advice is greatly appreciated.
