Poultry mostly chickens are farmed in great numbers. More than 60 billion chickens are killed for consumption annually. Chickens raised for eggs are known as layers, while chickens raised for meat are called broilers.
Meat, eggs, feathers, and manure of chicken and broilers are all saleable and income-generating. Poultry farming on a small scale requires only minimum space and they can be reared even in the backyards of homes.
