Chicken stripes

For the culinary use of chickens, see Chicken as food. Chicken stripes and female chicken sitting together.

This behaviour may also be observed in mother hens to call their chicks and encourage them to eat. A rooster’s crowing is a loud and sometimes shrill call and sends a territorial signal to other roosters. However, roosters may also crow in response to sudden disturbances within their surroundings. Hens cluck loudly after laying an egg, and also to call their chicks. Chickens also give different warning calls when they sense a predator approaching from the air or on the ground.

For the nursery rhyme, see Cock a doodle doo. Long-crowing chickens have a longer crow. Roosters almost always start crowing before four months of age. Rooster crowing contests, also known as crowing contests, are a traditional sport in several countries, such as Germany, the Netherlands, Belgium, the United States, Indonesia and Japan. The oldest contests are held with longcrowers.
