Gene-Edited Hens? They could prevent the slaughter of billions of male chickens

Researchers in Israel say gene-edited hens will prevent the slaughter of billions of chickens a year.

These researchers with the Volcani Institute developed a way for egg-laying hens to only lay female chicks. One of the scientists says it will revolutionize the industry.

The gene-edited DNA stops the development of any male embryos when the eggs are exposed to blue light over the course of several hours. The research was funded by animal welfare group Compassion in World Farming, and the scientists behind it plan to license the technology.
