Jaunty, this rooster steps away from us. The behavior and appearance of a rooster differs substantially from that of the hen. Roosters have a strong natural tendency to defend their territory, and they do so by crowing. The rooster begins crow when it is fully fledged, by 14 to 20 weeks, depending on the species. In free-roaming chickens, the rooster takes on a watchful role and warns for birds of prey and other danger. Unlike hens, which flee or remain silent in the face of danger, he makes himself great and even defends them against much larger enemies. When he finds a ´titbit´, he will initially call the hens with special cluck-sounds. If they do not come, as yet he will eat the snack himself and if the chickens quarrel with one another, he jumps in between, so a group of chickens with a rooster is usually quieter than one without.
