Only female chicks are hatched, and researchers breed genetically edited "Golda hens".

CTOnews.com, December 24 (Xinhua) Israeli researchers have successfully bred genetically edited hens that can only hatch female chicks. The British BBC reported that the scientific breakthrough could curb the slaughter of cocks, which are slaughtered every year because they cannot lay eggs.

Tuyuan DAVID AUBREY / SCIENCE PHOTO LIBRARY the project's chief scientist, Dr. Yuval Cinnamon of the Volcano Institute near Tel Aviv, told BBC News that the genetically edited hen, called "Golda hen", would have a huge impact on the poultry industry.

CTOnews.com learned that he said: "I am proud of the system we developed. I think it can really change the poultry industry, and the chicken is our first goal." Scientists have genetically edited the DNA of Goerda hens to stop the development of male embryos in their eggs. DNA is activated when the eggs are exposed to blue light for a few hours. The female chicken embryo was not affected by blue light and developed normally.

Tuyuan ORI PERETZ according to Dr Cinnamon, these chicks have no extra genetic material in their bodies, nor do they lay eggs. "for farmers, chickens are no different from those before, and consumers can get the same eggs," he said. it's just that the eggs need to be exposed to blue light in the production process.
