I have some shipped eggs in the incubator right now that has really huge air cells. I don't know if they will make it or not. I hope so. I have some lavender orp eggs in there and some Delawares eggs (both shipped eggs) that has huge air cells. The Delawares doesn't have as huge of air cells as the lavender orp eggs have. All the eggs arrived unbroken but the orp egg box was really beaten up with 2 sides completely smashed in.
