Sure, chicken rearing has always been a profitable business and I believe it would remain so for a very long time. I, personally have seen people that only rear chickens for a living and they are doing so well with it. You just have to be careful to keep the chicks from infections to enable them live and this way you are sure of making money.

With chicken rearing you can sell the eggs which they can produce a lot of it. You can sell the chicken raw or as roasted ones. You can even sell their deposits as manure even to farmers so it is a win win business for rearers.
