What is the term for the male chicken?

The term for the male chicken is "rooster." A rooster is the adult male of the species Gallus gallus domesticus, and the term is commonly used in poultry terminology to distinguish it from female chickens, which are referred to as hens, and younger, female chickens that are known as pullets. Roosters are known for their distinctive crowing and play an important role in a flock, often being responsible for protecting the hens and their chicks.

Capon refers to a male chicken that has been castrated, often raised for meat. While this term does relate to male chickens, it is more specific and does not represent the general term for male chickens as a whole. Hen specifically identifies female chickens, and pullet is a term for young female chickens, typically under one year old. Thus, "rooster" is the most appropriate and widely recognized term that directly describes an adult male chicken.
