Poultry business is a very lucrative business but you need space. You know the horrible smell that comes from poultry, neighbours will complain and even report you. So you need to rent or lease a space at the backyard of your building or if you have your own property, it is better. Then you deal with layers which lay eggs and broilers which is the one with big thighs and wings.
A good generator, water supply and then you stock enough feed to last for some weeks after you start because you won't start making money immediately you start. It is always advisable to buy the chicks at from 4weeks old.
