Gamecocks, also known as fighting cocks, are breeding lines that have been specifically bred and trained for cockfighting, a blood sport that involves two roosters fighting until one is dead or too injured to continue. Other synonyms for gamecocks include game fowls or just simply game birds. These birds are typically larger and more aggressive than other breeds of chickens and are often used for their meat and eggs as well. While cockfighting is illegal in many countries, gamecocks are still bred for other purposes and can be found in some rural areas as pets or for show in poultry competitions.
