Dec. 16th, 2007 11:03 amVent sexing is not easy. The sexual organs of birds are located within the body; the professional vent sexer has studied their external appearance, which can fall into as many as fifteen basic patterns, and learned to identify which ones are male and which female. Vent sexing is a difficult trade to master; many professional vent sexers are Japanese, where the art originated. The mystery of vent sexing was revealed to the Western world when a seminal paper was published in Japan in 1933 by Professors Masui and Hashimoto, which was soon translated into English under the title Sexing baby chicks. After Masui and Hashimoto's discovery, interested poultry breeders brought in people who had been trained by them to teach the art, or sent representatives to Japan to learn it. The skill is complex and has been likened to skill at playing chess and other crafts or games where pattern recognition is the key to success.
