1. A method of raising poultry comprising:
a. providing a plurality of poultry;
b. automatically controlling in a presence of the plurality of poultry a light beam including wavelengths in a visible light spectrum during a plurality of environmental enrichment sessions at spaced-apart predetermined session times per day;
c. the plurality of environmental enrichment sessions effective for improved poultry production performance without sacrificing poultry physical or environmental quality measures, wherein each of the plurality of environmental enrichment sessions comprises:
i. projecting the light beam to produce a light dot at a surface at or around the poultry during the predetermined session time; and
ii. moving the light dot along a path with randomized direction and speed relative the surface during the predetermined session time.
