I used to spend majority of my Summer each year (when I was a pre-teen) in a very poor South Indian village where my extended family lived. Our family owned a large flock of chicken. I enjoyed feeding the chicken, feed like rice, maize, wheat, etc., though for the most part, the chicken did not expect to be fed anything. They would just graze on whatever they found. Now that I look back, interestingly, every family (even the poorest) in that village owned a flock of chicken. It was as though the flock of chicken was one common thread that ran through every household in the village. At the time though I didn't have the sagacity to realize the economic incentives of owning a flock of chicken.
