Layer hens are chickens specifically bred for egg production. They are known for their high egg-laying capacity, often producing over 300 eggs per year. These hens are typically kept in commercial farms, where they are raised in controlled environments to optimize their health and productivity. The most common breeds of layer hens include Leghorns, Rhode Island Reds, and Plymouth Rocks. Layer hens are usually kept in large flocks and require a balanced diet rich in protein and calcium to support their egg-laying needs. Proper care and management are essential to ensure their well-being and maximize egg production.
