A cock, commonly known as a rooster, is an adult male chicken. They are known for their distinctive crowing, which typically occurs at dawn but can happen throughout the day. Roosters have bright plumage, often featuring vibrant colors, and are recognized for their prominent combs and wattles. Roosters play a vital role in chicken flocks, often serving as protectors. They help to alert hens to potential dangers and can also establish a social hierarchy within the group. In addition to their protective role, roosters are known for their mating behaviors, which include courtship displays to attract hens.
