Through a special structure in the egg, the CORION, which is a membrane that allows gas exchange with the outside. In a similar way, excretion substances accumulate in another structure, the AMNIOS. Embryos have the same metabolic needs as adults, only they solve them a different way.

They dont. Just like human embryos dont breathe. Everything that a chicken embryo needs is in the egg.

The eggshell is pitted and it is very thin. The baby chick breathes through the membrain that surrounds it.
