Is there such a thing as rooster chicken?

Here's why:

* Rooster is the male of the chicken species.

* Chicken is a general term for both male and female birds of the species *Gallus gallus domesticus*.

So, a rooster is simply a male chicken. There's no separate breed or type of chicken called a "rooster chicken".

However, you might hear people use the term "rooster chicken" colloquially to refer to:

* Older, mature male chickens: These chickens are often less tender and have a stronger flavor than younger hens.

* Meat from male chickens: This is sometimes sold as "rooster meat" or "cock meat" in some parts of the world.

If you're looking for information on a specific type of chicken, be sure to use a more accurate term like "rooster" or "hen" when you're referring to the gender of the bird.
