When candling eggs, how can you tell if the air cell has been pipped?

    When candling my duck egg, i recently saw that the shape and size of the air cell had changed from being straight across to slightly tilting and slightly larger - does this signal that the chick has broken into the air cell?

    No, this is quite normal. As you progress through incubation the air cell changes from small to big to being angled, if it is near hatch time and you see a beak inside the air sac then it has pipped.
    Good luck,
