A male chicken is called a cock or rooster. It is also significantly larger than the female. The red crest on the head and the wattle are typical characteristics of these animals. The top of the comb is especially large. Domestic chickens are birds that live most of their time on the ground. They cannot fly very well, but run very fast. They can only see well at close distances. They cannot identify anything farther than 50 meters away. Chickens eat plants, meat, fish, grains, insects and worms. The domestic chickens live mostly outside on the lawn. At night they need a stable, where they are protected from the predators and the cold.
