Chicken equipment - how to choose a cage for chickens to have cost-effective?

Broiler cage cage equipment and efficiency of equipment directly related farmers a lot of chicken farmers brood incubation and imbalance between layers, and do not meet the requirements. The feeding area is often too small, the feeding density is too large, and the feed and drinking water tank is not enough. It can be said that this is a common problem of chicken farmers, but also one of the important factors affecting the economic benefits of hens. There are also some chicken households for more chicken, less room or no more premises to support chickens, premature feeding the cage on chicks, the growth and development of young chicks unfavorable, and ultimately affect the laying performance of hens. Layers are harvested after the hen is laid.
The quality of poultry equipment is not matched, and the equipment for raising chickens, breeding chickens and laying hens has specifications and proportions. The equipment should be matched to the chickens, normal growth and reasonable turnover, give full play to the equipment utilization rate and operation rate, make the allocation in each hen or egg per kilogram of the depreciation fee is reasonable, which can reduce the production cost.
Cage support equipment for Broilers
Now many hens in cages, is indispensable equipment, chicken farmers are generally more attention. But the lack of ability to identify hencoop tend to buy quality, low price. The cage is for the life and production of hens and a place to sleep, can not neglect its quality, quality, the bottom of the cage cage width and slope is especially important. I have been in the same farm, witnessed the difference from two manufacturers hencoop quality, resulting in egg production, mortality and the number of broken egg rate has significant difference. Another common problem to note is that chickens are not packed in cages. When the survival rate of the brood is high, the number of the surviving hens exceeds the budget transfer group, or the group will not be able to phase out the underweight hen, which is often over loaded. According to statistics, when the number of cages per cage was increased to 5, 22.5% of hens died before 305 days. According to the production statistics accumulated over the years, cage density exceeds the prescribed standard of chickens, laying rate than the normal chickens 5% ~ 15%.
