People raise chickens all around the world under widely varying cir- cumstances. Their main objective is generally the same: maximum production for minimum costs and with minimum risks. The two main forms of keeping small-scale chicken are small-scale subsistence farming and commercial farming. If poultry is mainly kept for home consumption of eggs and meat, costs and effort can be kept to a minimum. But for a poultry enterprise to be successful, it must have a reliable market for its products and a steady supply of reasona- bly priced quality feed. It is important that feed resources are locally available. See figure.
