A cock is the male of any type of domestic fowl, and cockfighting is a blood sport in which two (or more) cocks are placed in a ring or confined area and encouraged to attack or fight each other. Cockfighting is illegal in all 50 states and the District of Columbia—but remains legal in Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands.

Although cockfighting is illegal in all states, the potential punishment for the crime varies from state to state. In thirteen states, a first offense charge of cockfighting is a misdemeanor—including Alabama, California, Hawaii, Kentucky, Louisiana, Mississippi, New Mexico, Ohio, South Carolina, South Dakota, Tennessee, Utah, and West Virginia. But in California, Louisiana, and New Mexico, second, third, and subsequent offenses may be prosecuted as felonies.

And some states also prohibit possession of cockfighting tools (implements) such as a gaff or slasher; ownership and training of cocks for the purpose of cockfighting; and attending cockfighting events.
Cockfighting laws are generally located in a state’s statutes—and usually in the state’s penal or criminal code.

In Illinois, cockfighting is illegal and is considered a serious offense. Under Illinois law, cockfighting is classified as a felony. This includes not only participating in cockfighting but also the possession of birds for fighting, possession of cockfighting implements, and being a spectator at a cockfighting event. The Illinois Animal Welfare Act specifically prohibits these activities. The penalties for engaging in cockfighting activities can include fines and imprisonment, reflecting the state's commitment to animal welfare and the prevention of animal cruelty. The exact penalties can vary based on the specifics of the offense, including the number of animals involved and the presence of prior convictions.
