When raising poultry what costs versus income can one expect? About how much food do the consume? How much should I expect to pay for caging and equipment to start each pair or trio? How much can I expect to get in return? What are the best breeds to get into with a good "payback" per bird when it comes to raising chicks, started adults, and fertile eggs (I am currently raising silkies). please note I'm not looking for them as an income source, but to help 'give back" from the feed and care I provide so that I can expand and invest in more and better equipment.
