Photoperiod Management Artificial lighting programs significantly influence egg production by regulating reproductive hormones. Layers require a minimum of 12–14 hours of daily light to stimulate egg-laying, with longer photoperiods (e.g., 16–18 hours) improving production rates in both chickens and turkeys. For example, extending daylight to 18 hours in turkeys reduced photorefractoriness and increased egg production…

The use of red light in chicken coops has been studied for its potential effects on growth, behavior, and welfare in broiler chickens.
