Does a newly hatched chick have the same nutritional value as an egg?

During growth, the chicken embryo is burning off some of the stored energy in the yolk and white instead of converting it to body mass.  Since they're aerobic organisms, that entails taking in oxygen from the outside, and converting some of the carbon in the egg into carbon dioxide, which diffuses out through the shell.

If we're just talking about calories, the hatchling will definitely have fewer than a freshly laid egg.
