So I find that to be confusing. If you had a huge air cell, why would they not have room to turn and get to it? What caused them to be stuck?
The humidity was TOO low, which allowed too much water to evaporate. The aircell was big and the inner membrane was basically pushing down on the chick. The membrane shrinkwraps around them because there isn't enough fluid left in the egg.
-The opposite is when the humidity is TOO high and the aircell can't grow. It stays too wet inside the egg and the chicks drown (when they grow in the fluid little egg) and they get a beakful of water instead of air at the time they pip.
