Genetically “Tweaked” Chickens Suffer from Lack of Fertility: Is the End of Commercial Poultry Near?

A Reuter's story recently reported that the world's largest chicken breeder is suffering from rooster infertility due to genetic manipulation. The popular Ross male breed of roosters is used to produce as much as 25 percent of the nation's chickens raised for meat (broilers). As a result, chicken production is down, and prices will continue to rise. So what are these "genetic manipulations" causing these problems? There is supposedly no GMO chicken in the market, but chicken genome has been mapped since 2004. Has the public actually been eating GMO chicken for some time now? What is the future of the commercial poultry industry and their factory birds?
