Embodiments described herein provide systems for stimulating a desired response, such as ovulation and egg laying, hunger, growth, mood and sexual maturity in birds, such as chickens, turkeys, ducks, quail and ostrich, by controlling the duty cycle, wavelength band and frequency of photon bursts to a bird, through the high frequency modulation of photons in an individual color spectrum to the bird and duty cycle, where the photon modulation and duty cycle is based upon the specific needs of the bird.
