Also the chicken business makes perfect sense. If you keep chickens you can sell eggs, then eventually sell poultry, then eventually save enough to buy/sell goats or buy a cow for milk.
For a poor rural family having access to eggs, milk and the occasional chicken curry is a big benefit.
One of my cousins married a girl who's parents are small farmers. They like us were migrants of partition and they lived in Punjab on someone's land. As people left for abroad they found an opportunity. They'd farm the abandoned lands and pay the owners a share of profits from the crops. With this money they bought cows and sold milk, goats and sold meat, chickens and sold eggs and poultry. Eventually they bought land of thier own and also leased land as they were doing. They saved up to buy tractors. Within 2 generations they made enough money to buy land, build houses, afford cars and motorbikes, this own tractors etc, own farmland. Today other people work for them on thier lands. Thier third generation is now working there.
