Hi Hajira,
Breeding country chickens is the most easiest if you have a good free sapce and little number of chicken and a sleeping shed for them.
To be accurate, we suggest a shed space of 2.5 square feet for country chicken to be bred always inside the farm or a shed space of 1.5 square feet if the country chicken in going to be free ranged.
We lost a lot of money initially buying feed. I will be polite here; These feed manufactures are mostly suguna, skm, godrej. They sell the feed at a cost which ordinary small farmers cant afford. also they dont display the feed ingredients and actual protein, fat, calcium-phosphorus ratio, energy levels, vit-min levels and have no other certification from government.
So after losing so much of our hard earned cash, I got enlightened one day!!!
I started observing country chickens going all over my near by villages. They were growing chickens so effortlessly. It was then I realized, that the knowledge of chicken rearing I learnt about broilers was the main hindrance to country chicken growing.
Any Pure breed of country chickens knows what he/she wants. These fellows are really intelligent. They just eat what is tasty, healthy, alive, fresh. Please dont ask me why they drink dirty waters in streets
So I started giving them a mix of fresh spinach by buying at low prices from the farm, coriander leaves in big bags, waste fruit pulp from Juice shops, sprouted grains, mashed corn, sorghum and free ranging them. They gained low weight due to free ranging them. I dont care. I am not to fatten them. The eggs tasted very much tasty after that.
So feeding them depends on your choice. If you find the above crude process a lot of work, you have a choice!
Also I would like to state some batches of our early chickens raised with company feeds gave good result and with same feed, the next batch faced problems due to high dried fish content.
If you are serious about country chickens, build a small farm to hold 50/100 chickens initially and buy pure country chickens to hatch their own chicks or buy pure country chicks for uniform chick development and sell them at the same time and clean your farm afterwards. Then replenish your chick stocks.
