Hens are female chickens, commonly raised for their eggs and meat. They belong to the species Gallus gallus domesticus and are known for their distinctive clucking sounds. Hens typically have a plump body, a small comb on their head, and feathers that can vary in color depending on the breed. Hens are social animals that often live in flocks. They require a balanced diet, including grains, seeds, and greens, to stay healthy and produce eggs. The average hen can lay about 250 to 300 eggs per year, making them an important source of protein for many people around the world.
