Interesting on your feed ingredients. Several people have been looking for a formula for homemade feed.
I looked into buying ingredients and it cost more here than buying premade.
I buy a mash from a local farmer. I ferment it overnight so the fines stick to the bigger pieces.
We are subsistence farmers. We grow most of what we intend to consume. We grow rice, wheat, corn, sorghum, millets, pulses, sugarcane, fruits, vegetables, some spices like coriander, turmeric etc and green fodder for buffaloes. So you see we are trying our best that we don't have to buy bread from the market, under these circumstances it will be outlandish to think that we will buy food for our chickens.
We sell excess in the local market and buy essentials. I hope you understand that farming has never been a profitable endeavour, anywhere in the world. Even huge farms in US run on government subsidies. Here almost all farmers send away their working age sons to big cities so they can earn and send some money back so the family can live a decent life and we are no exception.
