I have 2 eggs that were set to hatch today. The first chick has externally pipped but the 2nd egg looks very odd. It hasn't looked right for the past 4-5 days or so and I thought that the embryo had died but I finally saw it move tonight and definitely heard it chirping. The air cell has looked huge for a while despite humidity around 40 percent (it had been higher before as I am incubating and hatching in the same incubator at once.) Now the air cell is even larger filling nearly half the egg, I can clearly see huge veins but barely see the chick; it is chirping loudly and it is not in the air cell. Anyone have any ideas of what is going on?
