Officially a female chicken is called a pullet until one year of age. Being broody means that the hens system has an increase in hormones which causes the hen to sit on eggs for three weeks until she can hatch them and become a mother. While sitting on eggs, she does not lay eggs, get off the eggs once a day to eat,drink and poop. If you do not want your chickens to become mothers because you already have enough chichens and just want her to lay eggs, you need to try tricks to change her.
So a broody hen is called a broody for short. Male chickens are cocks until one year of age and then they are called roosters. We all do not want or need many roosters, so if you plan on keeping chickens be prepared to "harvest" or process young male birds and/or old hens who do not lay any longer. This is only practical since feed is expensive. In my opinion once you buy animals, you are responsible for them.
