Research has emerged from Edinburgh University’s Roslin Institute, famously behind Dolly the sheep, that has taken the first step to genetically modifying chickens to lay eggs from a different species.

Scientists at the Institute have already used the technique to create a chicken fathered by a duck, and a large bustard fathered by a cockerel. It is hoped that the technology will enable the repopulation of endangered or extinct species.

This, according to a spokesman, could include rare ducks, songbirds… or even raptors.
