The female reproductive tract of chickens consists of a pair of ovaries and oviducts. The egg travels through the oviduct over approximately 22 hours, undergoing several modifications. It passes through the infundibulum, where it is engulfed. In the magnum, albumen is deposited on the egg. The isthmus adds two shell membranes. In the uterus or shell gland, calcite crystals are deposited to form the eggshell. A protective bloom coating is applied in the vagina before laying.
