What is the reason why laying hens start late?

Laying hens are basically raised in all parts of our country, which is an indispensable kind of poultry. Because laying hens are raised mainly for eggs, chicken farmers attach great importance to the opening time of laying hens. However, many people find that sometimes laying hens start relatively late, which causes great losses to their breeding benefits. So what is the reason why laying hens start late? Today, the editor will give you a brief introduction. Let's take a look at it.

1. The tibia is not long enough.

For laying hens, the length of tibia is one of the most key indicators that directly affect the ability of laying eggs. When many chicken farmers are raising chickens, they basically do not know this indicator. And in order to reduce the breeding cost as much as possible, but did not strictly feed the full-price feed according to the requirements, resulting in insufficient feed nutrition. This affects the development of tibia in laying hens and leads to excessive tibia in chicks before six weeks of age. If the brown-shell laying hens are about two months old and want to start laying normally, the length of the tibia should be at least 80mm. If it is too short, the laying time of the laying hens will be delayed.

2. Immature development

Laying hens have great requirements on weight and evenness at the beginning of laying. If they are not evenly distributed, the laying peak of laying hens will be delayed by about three weeks. And if the evenness is poor, then the death rate of chickens during the reproductive period is also very high. The peak time of egg laying is also relatively short, and the benefit of breeding is poor. In addition, if the time of sexual maturity of the chickens is not the same. As a result, some chickens start laying early and some chickens start laying late. Then the laying peak of each chicken in the flock will be different, and there is not a concentrated peak of laying eggs.

3. Improper management in the later stage of development.

After the laying hens enter the breeding period, the evenness of the flock will have a direct impact on the future egg production. However, we should not pursue uniformity too much, which is also very bad for the growth of laying hens. During the breeding period of laying hens, many chicken farms feed blindly and do not adjust the feeding density in time, which leads to poor performance of laying hens. After finding the problem, we blindly pursue its evenness. There is not a reasonable management plan for chickens, blindly feeding and cutting. As a result, many heavier chickens are unable to survive due to lack of nutrition, while some low-weight chickens can gain weight, but most of the increase is fat, so they can not start production in time, resulting in a delay in the opening period.

4. Unreasonable lighting

Light has a great effect on the opening time of laying hens. In the breeding period of laying hens, it is generally in the stage of gradually lengthening the light time, which is very beneficial to the sexual maturity of laying hens, and it is easy to start early. If the light time is shortened gradually, it is very disadvantageous to the sexual maturity of laying hens, especially at the beginning of sexual maturation after 15 weeks of age. If there is not enough light, it will affect the development of the reproductive system of laying hens, thus delaying the start of production. And light intensity is also very important, if the light intensity is not enough, it will delay the laying time of laying hens.
