Do eggs need oxygen to hatch?

Ventilation is very important during the incubation process. While the embryo is developing, oxygen enters the egg through the shell and carbon dioxide escapes in the same manner. As the chicks hatch, they require an increased supply of fresh oxygen.

How do you know if a chick has died in an egg?

You'll be able to tell when it died depending on whether there is still yolk in the egg, or if it has been fully absorbed into the body (as it will be when the chick starts pipping).
