Which type of chicken is known for being smaller than standard breeds?

The bantam chicken is recognized for being smaller than standard breeds. Bantams are essentially miniature versions of larger chicken breeds and can be found in nearly every breed. Due to their size, they are often kept for ornamental purposes, exhibiting and sometimes for companionship rather than egg or meat production. These small chickens are available in a wide variety of colors and patterns, making them popular among poultry enthusiasts and backyard keepers.

In contrast, the other types listed do not share the same characteristics as bantams. Broilers are bred specifically for meat production and are typically larger, while Plymouth Rocks are a standard-sized breed that is well-known for its utility in egg and meat production. Kabir is not a commonly recognized breed in the context of poultry standard sizes, further emphasizing the specific nature of the bantam as the correct choice in this question.
