I could really use some education on air cells. My duck has pipped the shell, about an 1/8 of an inch above the air cell border, if you can call it that. Before I locked it down, I drew a line showing where the air cell was - he has pipped just above it. Is this normal and good? He pipped about four hours ago and I have not seen any movement of the egg since.
