摘要

A chicken egg inspection device (2) is provided with a vibrating unit (3), a vibration detection unit (4), and a determination unit (5). The surface of an eggshell (E1) of a chicken egg (E) being inspected is vibrated by the vibrating unit (3). Vibration caused by the vibrating unit (3) is detected in the vibration detection unit (4). In the determination unit (5), whether or not the chicken egg (E) being inspected comes from a group of young chickens is determined on the basis of the rate of attenuation of the amplitude of vibration detected by the vibration detection unit (4).
