Item#: MIS450

The rectum needs to be opened by a squeeze, the sexer then placed over it and with the aid of the mirror which is fixed inside at a 45° angle. The checker then looks for a bump. If the largish bump is there the chick is male. Vent sexing was first introduced to the western hemisphere in 1933 after a paper on the subject was published in Japan.
