Comparisons were made of the relative stimulating potential of a model versus live hens utilizing two populations of chickens that differed widely in mating frequency. Chickens from both lines mated with the model significantly more than with the live hens. The frequency of courtship was reduced when the model was employed indicating that courtship is not a prerequisite to mating behavior and that a chicken model can be effectively used as a means of stimulating copulatory behavior.
