A poultry breeding method comprises the steps of providing a cage device for hens with an independent cage section so as to be free from contact with the other cages and auxiliary devices of the cage device, providing the independent cage section with a weight sensor for producing an electric signal representing the actual weight of hens housed in the cages of the independent cage section, applying the electric signal from the weight sensor to an electronic control device having stored therein ideal hen weight data relating to the hens housed in the cages, comparing the ideal hen weight data with the actual weight represented by the electronic signal, and using the result of the comparison for controlling the operation of a device for supplying feed to the hens. The method enables the hens to maintain at their ideal weight and their fecundity to be increased.
