What is the term for a mature male chicken?

A mature male chicken is specifically referred to as a rooster. This term is widely recognized in both agricultural and general contexts, distinguishing male chickens from females. Hens are the females of the species, while the terms tom or stud are not relevant to chicken, as they commonly refer to male turkeys or other animals. Understanding these terms is key in poultry science and management, especially in breeding and livestock classification.
