It depends on what kind of chickens are raised.

The cost of a quick-made white-feathered chicken is about 25 yuan, and the cost of a chicken house is about 20,000 yuan per 4,000 chickens;

The investment for native chickens is relatively small, and the space to build a chicken house is only With an investment of less than 1,000 yuan, the breeding cycle of each chicken is 6-8 months, and the cost is about 30 yuan/bird. If it is free-range and has other free sources of food, the cost will be further reduced.

I have never been exposed to special breeding pheasants, guinea fowl, etc. Generally, the local Xinhua Bookstore has relevant books for sale. You can go and read them for reference.

Hope it can help you!
