Commercial egg production in Utah has developed gradually since 1920. Production of eggs increased from 142 million in 1924 to 433 million eggs in 1946. The percentage of total farm income of the state derived from the poultry industry increased from 5.3 percent in 1924 to 23.1 percent in 1946 and at the present time constitutes the largest income of any farm enterprise in this area. Factors influencing this development are: 1. High prices resulting from the war period of 1917 to 1920 followed by the depression period when prices were low. 2. The organization of cooperative egg-marketing associations. 3. Shipments of eggs to the eastern markets. 4. The lack of marketing facilities for the high-quality eggs produced in the state.
