Re: Thinking it through
If Billy had actually spent some time living in a typical rural location where incomes are low and the work is hard and the people are many, he would have noticed that many of the people eyeing the chickens and deliberating on their culinary qualities are not necessarily their owners. Security costs a lot, and there are no police to investigate multiple cases of multiple henocide. Even chicken wire (netting) needs plenty cash, and it needs to be buried on on side to stop the rats and dogs... and the snakes... they come and eat your eggs and chicks. So the netting has to be the expensive sort with small holes. The edge in the ground rusts in a a short time and is impossible to mend... and anyway free-range chickens... even in a law abiding community with no rats, dogs or feral carnivores... will happily lay their eggs in any shady spot they can find... and you won't.
He would have also noticed the dire shortage of cooking fuel... have you ever tried to take a 3 year old garbage heap tart and "cook until tender". It takes a lot of wood. Great recipe for soil erosion.
Then there is the small matter of conversion efficiency. Humans can also eat the grains that go into the chickens, and many struggle to grow enough of that for their own consumption. But the conversion loss of food value after passing it through a chicken just compounds the problem.
Of course if Bill is looking to empower a business class to dominate the cereals market by driving up prices which they can recoup by feeding it to chickens to sell to the developing professional and entrepreneurial classes, where they exist, then he is likely to solve the development problem quickly. The demographics will soon show a surge in the percentage of the population in work and with their own business... the population will also be smaller, the rest will likely have starved to death.
