(1) full step
The upper cage and the lower cage are staggered, basically not overlapping or slightly overlapping, and the overlapping size does not exceed the width of the egg guard at most (Figure 10- 19). The supporting equipment of full-step henhouse is: chain feeder or rail car quantitative feeder, boat-shaped trough small-scale feeding and manual feeding; Drinking water can be cup type, nipple type or sink type. If it is a high-bed henhouse, the chicken manure will be removed with a forklift when the chickens are eliminated; If it is an ordinary henhouse, there should be a dung trough under the henhouse, and a scraper dung cleaner should be used to clean the dung.

The advantage of full-step henhouse is that chicken manure can directly fall into the manure trough, which saves the manure bearing plate between layers; Good ventilation and sufficient light. The disadvantage is that the cage group occupies a large area and the feeding density is low.
(2) Half step type
The upper and lower cages are partially overlapped, and there is a dung bearing plate in the overlapped part (Figure 10-20). Its supporting equipment is the same as the whole step. The chicken manure on the manure bearing plate is removed by scrapers extending from the two wings, and the scrapers are connected with the scraper-type manure cleaner in the manure box.

The semi-stepped henhouse group occupies a narrower area than the full-stepped henhouse group, and the feeding density in the henhouse is higher than that in the full-stepped henhouse group, but the ventilation and lighting are not as good as that in the full-stepped henhouse group.
(3) Laminated type
The upper and lower henhouses completely overlap, generally with 3-4 floors (Figure 10-2 1). Chain feeder can be used for feeding; You can use a long slot water dispenser to drink water; Scraper or belt cleaner can be used between layers to scrape chicken manure to one or both ends of each row of henhouses, and then the chicken manure can be scraped out of the house with a horizontal spiral scraper; Small chicken coops can be cleaned by a drawer-type dung cleaner, and the dung can be pulled out and dumped manually.

The advantage of stacked henhouse is that it can make full use of the ground space of henhouse, with high feeding density and high temperature in winter. The disadvantage is that there is a big difference in lighting and ventilation between the floors of the henhouse, and there must be manure bearing plates and supporting manure cleaning equipment between the floors, which brings inconvenience to the management of chickens on the upper and lower floors.
(4) Laminated synthesis
The top chicken coop and the bottom chicken coop form a ladder shape, and the bottom two chicken coops completely overlap. The bottom henhouse is provided with a dung bearing plate on the top net (Figure 10-22). The dung on the dung bearing plate needs to be removed by manual or mechanical scraper, and the dung conveyor belt can also be used instead of the dung bearing plate to transport the dung to one end of the chicken house. The supporting feeding and drinking equipment is the same as the full-step chicken house.

All the chicken coops in the above combined forms can be made into a half frame (Figure 10-23), and can also be made into two, four or more floors. If the degree of mechanization is not high and there are too many floors, it is not convenient to operate and observe the chickens. At present, most chicken cages produced in China are 2 ~ 3 floors.

(5) single-layer flat type
Chicken cages are placed on a plane, and there are no passages between cages. All operations, such as managing the chickens, are undertaken by the crane running above the henhouse (Figure 10-24). Its advantages are that the illumination and ventilation of chickens are relatively uniform and good; Because an egg collecting belt, an egg collecting groove and an egg collecting groove are used between two rows of chicken houses, equipment investment can be saved. The disadvantage is that the feeding density is low, and two rows of cages use an egg collecting belt, which increases the collision of eggs and has a high egg breaking rate.
