Ref the eggs, don't always take it as true that the chickens you see have produced the eggs you buy. As a mechanic who used to work on farm tractors and behind the scenes you see a different picture. You have a few nice chickens near where people stop to buy farm produce and hidden away is a batterry hen building containing about ten thousand hens. There was a pub that sold eggs 30 at a time and stacked about 10 trays high. Along side the pub were a few chickens and the bright people from the city never wondered how so few chickens produced so many eggs!
