Has anyone seen a hatching eggs with two air cells? I candled this egg, and at first figured it had to be the yolk, but it isn't. It is a separate air cell, or so I think. I am new to this and could be just ignorant about the whole thing. This is a shipped egg. All other eggs from this shipment have pristine air cells...which is so great! Outlined to show the air cells since my candling photo isn't very good.
