Was going to candle the eggs today, but the only thing I could see was the air sacs and large masses. I did mark the air sacs on the outside of the eggs. All of them were about the size of this one, probably 1/4-1/3 of the egg. All except for this one, which was smaller. Will the duckling still be able to pip and hatch, even though the air sac in its egg is smaller?
