Abstract: A method and system for monitoring the egg-laying performance of caged laying-hens at laying-hen positions are provided. A plurality of coops are disposed side by side, a conveyor belt is disposed below the plurality of coops, and a machine-vision inspection device having a CCD camera and a lighting device is provided on an output end of the conveyor belt. Eggs laid by the hens fall onto the conveyor belt from the bottom of the coops. After all eggs are laid, the conveyor belt is activated to convey the eggs to the machine-vision inspection device, and the CCD camera is triggered to capture an image of a surface of the conveyor belt carrying the eggs.
