I saw an episode of "Dirty Jobs" (Discovery Channel) and they humourously demonstrated and explained how the dirty job of "baby chicken sexing" is done. The episode first aired on Aug 16, 2003.
Yet, there article claims ...
"Chicken Sexer the chicks after a few days differ, although the sexual characteristics until after four weeks to train. If you ask these people how they do that, they can not explain it."
It makes me wonder if the rest of the article on stock-picking is similarly inaccurate.
