Before this, chickens did not thrive during the winter due to lack of sunlight, and egg production, incubation, and meat production in the off-season were all very difficult, making poultry a seasonal and expensive proposition. Year-round production lowered costs, especially for broilers. Artificial daylight supplementation also started being used.
