Gianni The Gender-Bending Rooster Baffles Scientists


Gianni started life as a red-blooded cockerel and would often wake his Italian owners up crowing on his farm in Tuscany. But when a fox raided Gianni's enclosure and killed all of the hens inside, Gianni felt it was time for a change. Within days the bird was laying eggs and trying to hatch them as he began his new life as a hen.

Gianni has baffled scientists at the UN's Farm and Agriculture Organisation, who are now planning to study his DNA to see what made him change. An expert at the centre said: It may be a primitive species survival gene. With all the females gone he could only ensure the future of his line by becoming female.
