Stacked chicken cages for free-range laying hens

Abstract

The invention belongs to a stacked coop for drylot feeding and cage-free feeding of laying hens, wherein the stacked coop is capable of improving the welfare state of the laying hens. The stacked coop comprises a trapezoid coop frame, wherein the trapezoid coop frame is laterally provided with an automatic excrement removing mechanism; the middle of the trapezoid coop frame is provided with a transverse brace; the middle of the transverse brace is provided with bottom nets which are parallelly arranged in the vertical direction; the front of a space between two adjacent bottom nets is provided with a net-shaped step; leakage slots are formed between the net-shaped step and the bottom nets; two ends of the net-shaped step are connected with the transverse brace; the front end of the transverse brace is provided with perch; the upper left end of each bottom net is provided with a laying nest; the trapezoid coop frame below the bottom nets is provided with a drinking trough; a material trough is arranged at the lower rear side of the drinking trough. The laying hen movement space is enlarged, so that the laying hens can take food and drink water on the bottom nets and lay eggs in the laying nests; the laying hens can move conveniently in the stacked coop due to the net-shaped step and the perch, so that the living welfare of the laying hens is improved; the automatic excrement removing mechanism is capable of removing excrement of the laying hens in time, so that the laying hen feeding environment is effectively improved and the eggs are prevented from being polluted by the excrement.

Description

technical field [0001] The invention belongs to a chicken cage, and in particular relates to a stacked chicken cage for rearing free-range laying hens which can improve the welfare state of laying hens. Background technique [0002] Since the 1950s, the cage feeding method of laying hens has been widely implemented. Until now, cage feeding has been the main feeding mode of laying hens. Cage feeding has the advantages of improving efficiency and reducing feeding costs. It is easier to handle, reduce feed waste, check the condition of each bird, etc. With the increasing scale and intensification of laying hens, at present, laying hens are kept separately in chicken cages in chicken houses. The method can increase the stocking density of laying hens and thus increase egg production. However, due to the restricted activities of laying hens in the chicken cage, they cannot normally stretch or flap their wings in the cage, or even turn around, and cannot peck their own feathers....

AI Technical Summary

Problems solved by technology

However, due to the restricted activities of laying hens in the chicken cage, they cannot normally stretch or flap their wings in the cage, or even turn around, and cannot peck their own feathers. They are always in a state of helplessness, let alone express their nature freely. The laying hens are irritable, prone to some bad habits such as feather pecking, toe pecking, anus pecking, etc., and even fights, which greatly damages the welfare of the laying hens. At the same time, due to the long-term lack of exercise of the laying hens in cages, their bone strength The lowering will lead to common cage fatigue in laying hens, causing laying hens to be unable to stand up and eat and drink water, reducing the egg production and egg quality of laying hens. In addition, the increase in the breeding density of laying hens will inevitably increase the number of chicken cages. The air circulation in the house is affected, which can easily cause the indoor air to be cloudy and cause diseases
