Does an air sac mean the egg is fertile and developing?

    We're only on day 3 but I looked at a few of the eggs today and can see an air sac on the end. Does that mean we have a chick starting to develop or do all eggs develop that sac while being incubated?

    No. Aircells will get larger as an egg gets older anyway. You should not candle this early--the embryo is too delicate. Wait till at least a week or ten days, then you'll be able to see something.
