Dear venkat,
You can opt for chicken retail shops. What you need is ventilated hygienic shed, small area to stock 100 live chicken, water facility, Chicken feather deplitator and 3 workers (if you wish to be a worker then 2 is enough).
If you already have a building or shed, with water facility, Initial investment would be around Rs. 10000/- or even less.
Remember that Chicken retailing shops get beautiful returns and that too immediate money in hand.
PM me more details
