According to Ta Kung Pao's report on April 22, Jenny, a rooster in Italy, suddenly became a mother capable of laying eggs and hatching little chickens. Its owner said Jenny's "transsexual" situation happened after a foxes' attack and all the hens were eaten.

From Jenny's looks, it is still a rooster, but the fact that it could lay eggs confused FAO experts, and they are working hard to understand the phenomenon.

As of now, experts believed it is a genetic mutation. When all the hens died in Jenny's living circle, it had to carry the responsibility of continuing its own species.

Later, experts will take Jenny to UN's laboratory for more research and analysis. And they said study on Jenny might help to figure out the puzzle: "Which comes first? The chicken or the egg?"
