The three major systems under which poultry farming is practiced are extensive system, semi-intensive system, and intensive system. The extensive system, also known as free-range poultry farming, is one of the oldest methods of poultry rearing and is commonly practiced in rural areas.

The birds feed on natural resources such as insects, grass, seeds, and kitchen waste, which reduces the cost of commercial feed.

Despite these limitations, the extensive system supports rural livelihoods and promotes sustainable backyard
