There are 5 eggs that have pipped, 4 have pipped in the air cell & 1 has pipped at the other end of the egg. Not in the air cell. Pipped the pointy end of the egg. ( I marked on all the eggs where the air cells are so i would know how big they are.) Some air cells are big/almost half the egg. Is this bad? ~ Just recently this egg had pipped & i seen the egg still moving. There isnt much room in that egg dont know how it could pip there. ~ IS THE BABY UP SIDE DOWN? Thanks, ~Julie~
