A: The eggshell is produced by the uterus of the bird. The mineral involved is mostly calcium carbonate that the female gets from her diet (about 2/3), but the rest (1/3) is removed from her bones.
The shell quickly hardens (within minutes) as it is being laid down around the egg yolk and egg white (albumin). This takes place within the female's body.
Yes, the egg is fully developed BEFORE it is laid.
