Scientists discovery mystery behind half-female, half-male chicken
Yes, the news here is actually NOT that there are half-female/half-male chickens running around and it's fairly common (one in every 10,000 chickens), but that scientists figured out the reason behind the sexual duality is cellular, not hormonal.

Last September, New Yorker staffwriter (and former Phoenix staffer) Susan Orlean laid out the case for keeping fresh poultry in the backyard: it's cheap, it's safe, it's fun, and it's environmentally sound. You would think that would be enough for the city fathers of Cambridge, Massachusetts.
