(1) Existing problems:

What are the advantages and disadvantages of stacked chicken coops? What is the depth (600mm, 620mm, 750mm), height (430mm, 450mm), single cage feeding capacity (6, 8, 10), and cage spacing? How to solve the problem of chickens running out of the cage and running around the cage? How effective is the use of this cage to raise breeders?

(2) Solution:

It has been pointed out that layer hen cascading cage has the following advantages: saving land occupation, reducing civil construction investment, and large feeding capacity per unit area; High degree of mechanization, reducing labor intensity and labor costs; The environment of the chicken coop can be controlled artificially to reduce the impact of the external environment on the chickens; Chicken manure can be treated in time to reduce environmental pollution. There are also the following disadvantages: strong dependence on energy; Relatively high energy consumption; The high density of single houses increases biosecurity risks.

It has been pointed out that the cage spacing should be moderate, otherwise it will affect the growth of chickens, and running chickens and running chickens can be achieved by adjusting the height of the baffle. In addition to considering the investment cost, the convenience of the equipment should be considered, if the cage depth is too large, it is not convenient to catch chickens and maintain the waterline. For this cage, manager Hu Yonglin pointed out: from the practice of Huayu Company in raising parent breeders, the hens in the house can produce 220 eggs and 40 commercial eggs, and the average fertilization rate of eggs can reach more than 94%, the hatching rate is also good, the average 2.42 eggs can hatch 1 healthy female chick, but there are also some shortcomings in the use of this cage, such as high death rate of breeders, large amount of roosters, etc.
