What are the two main components of a hen's reproductive system?

The two main components of a hen's reproductive system are the ovary and oviduct. The ovary is where eggs are produced; it contains a series of developing follicles that will eventually mature into eggs. The oviduct is a crucial part of the reproductive tract where the egg travels after being released from the ovary. In the oviduct, the egg is fertilized (if sperm is present), and layers of albumen (egg white), membranes, and eventually the shell are added, culminating in the formation of a complete egg ready for laying.

Understanding this system is vital for poultry management, as these components directly influence egg production and reproductive health. The ovary and oviduct work in harmony to ensure the regular production of eggs, which is fundamental for both commercial operations and backyard poultry keeping. Other options do not accurately represent the complete structure and function of the hen's reproductive system.
