Years ago, I started to study Traditional Chinese Medicine to expand on my Massage Therapy License and begin practicing Acupressure and acupuncture. I came across a copy of an old manuscript in an old text that showed how they sexed chicks thousands of years ago. A new chick, pick it up by either the scruff of the neck and let it hang for a moment, or grasp their feet and let them hang upside down for a moment. females will curl themselves up into a "C" or a ball, males will just hang straight. I used this method a few times and it always seemed to come out about 50% of the time (Great odds, I know.. ) Typical for any method other than actual vent sexing. I was wondering if anyone else had heard of this method and what they thought?
