Answer:

The eggshell is produced in the uterus or shell gland by the deposition of calcium carbonate. The eggshell formation roughly takes about 20 hours. Calcium is deposited onto the shell through the blood stream. Eggshells in high productive laying hens contain between 1.7 to 2.4 grams of calcium (average of 2 grams).
