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。

意大利托斯卡纳养鸡场的公鸡詹尼突然自动“变性”成为“妈妈”，不但每天下蛋还会孵蛋。据场主介绍詹尼的“变性”发生于场里所有的母鸡被狐狸偷吃掉之后。

　　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。

詹尼的外貌还是公鸡的样子，但是它却会生蛋和孵蛋。此事让联合国粮农组织的专家感到不解，正在研究詹尼变性的原因。

　　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。

目前，专家初步判定，这是“生存基因”作祟。由于当所有的母鸡挂光光，詹尼为了救亡图存保后代，只好自兼皇上和后宫佳丽了。

　　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?"

　　专家将会把詹尼带到联合国的实验室作详细分析及研究。专家指出，这项研究将有助解释“鸡先还是蛋先”的难题。
