The purpose of a ration for egg production is two-fold. First, it must furnish the heat required to maintain the body temperature of the chicken at about 106.7 degrees. In addition, the birds need feed for energy and other materials necessary for the maintenance of the body and health. After these body requirements are met, and if proper nutrients are available, the remainder of the feed can be used for the production of eggs. Birds in good production require about two-thirds of all the feed they eat to maintain their bodies. Thus, it can be seen that about one-third more feed will be required to produce 100 to 150 eggs in a year. This amounts to around 30 pounds of feed. If no eggs are obtained, it will take around 50 to 60 pounds of feed to maintain one bird for a year. Most of this is wasted, since the hen will not gain much weight during the year.
