In addition to making gradual changes to the lighting program itself, making a gradual change to the state
of night (darkness) or day (light) may also be beneficial. Feeding activity in broilers is at its highest level
immediately after the lights go on, and for a period (of approximately 1 hour) before lights go off. The use of
dawn to dusk systems (initiating day time or night time over a period of 15 to 45 minutes) will result in birds
gradually moving towards the feeder and can help alleviate crowding.
