Has anyone ever heard of the old wives tale that if you hold a chick upside down by the legs you can tell the sex? My mother told me that if you hold them upside down the hens will hang straight and the roos will flap up and try to correct themselves. I am actually tried this method at TSC on some straight run bantams. Out of 5 "hens" I got three hens and two roos! I never believed this and still do not, but my mom swears by it!
