First of all, it depends on whether Yunnan is suitable for black-bone chicken breeding. If the initial investment is calculated according to the cost of a chicken 4-5 yuan, then 1 1,000 chickens will be 4,000-5,000 yuan. If the site construction is calculated according to the 20 yuan of one square meter, the site area of 500 square meters is 1 1,000 yuan. Feed can be purchased directly from feed factories or feed shops, and there is special chicken feed. If properly reared, the 20 yuan cost per chicken is 20,000 yuan, and the feeding tools 1000 yuan. The total investment of 1 000 chickens should be 1 000+20,000+1000 = 3 1 000.
