There were actually Mutant Chickens that weren't afraid of the virus? This isn't just a safe bet; more importantly, with the Zombie virus everywhere, raising these Mutant Chickens means no need for feed! How much grain would that save? This is like a walking meat locker in the apocalypse! And it's self-preserving too!
It's a pity, though. This ten percent hatching rate is a bit too low; it's doomed not to be widely developed, Jing Shu thought, shaking her head. She had chosen the premium route. If she were to raise tens of thousands of chickens in a mass-market approach, by the fifth year, there wouldn't even be a need for the tyrant to reap the rewards. Jin Tianci would probably covet such a batch of Mutant Chickens that could survive in the apocalypse.
So they had to be rare. They needed to be rare enough to have only a few slots per month for reservations and so rare that they would become a protected species, requiring the Government to intervene and protect them.
