With the rapid development of the chicken industry, the market has put forward higher and higher requirements for the output and quality of eggs, so the breeding of laying hens has become the key to egg production. Next, in combination with the actual production, the chicken cage supplier will talk about the management of the breeding eggs.

Although the hens who have just started to lay are sexually mature and begin to lay eggs, the body has not yet fully developed. The body weight is still increasing at the age of 18 weeks. The growth and development basically stops at the age of 40 weeks, and the weight gain is very small. After 40 weeks of age Most weight gain is fat accumulation. Laying hens of different ages have different utilization of nutrients. When the hens just reach sexual maturity (17-18 weeks of age), mature ovaries release estrogen, which significantly increases the hen's calcium storage capacity, and starts to lay to the peak of laying. During the period, the chicken's ability to digest and absorb nutrients is enhanced, and the feed intake continues to increase, until the late stage of laying, the digestion and absorption capacity is weakened, and the fat deposition capacity is enhanced.

In the first 3 to 5 days before the transfer, prepare and disinfect the laying hen house, and do the immunization and repair work of the reserve hens before transfer. Regarding the timing of transfer, due to the results of recent years of breeding, the age of chickens has been brought forward. The transfer should be carried out at 16 weeks of age. When the chickens are between 17 and 18 weeks of age and their body weight reaches the standard, they will be replaced immediately. Egg feed can increase the calcium reserves in the body and allow the young hens to store sufficient nutrition and physical strength in the body before delivery.

Practice has proved that according to body weight and sexual development, changing the egg-laying feed earlier is beneficial to future egg laying. Using calcium feed too late will cause paralysis and produce soft-shelled eggs. The start of labor is a major turning point in the life of a young hen, and it is a great stress. During this period of time, the reproductive system of the young hen matures rapidly, and the weight of puberty still needs to increase continuously, roughly 400～500g. The egg weight gradually increases, the egg production rate rises rapidly, and consumes most of the hen's physical strength. Therefore, it is necessary to reduce further interference to the chickens from the outside as much as possible, reduce various stresses, and provide the chickens with a peaceful and stable living environment , And ensure that the nutritional needs of chickens are met.

The light management during the laying period should be consistent with the light during the rearing period. Raised in an open chicken house, if the transfer group is in the season of gradual increase in natural light, and the chickens fully adopt natural light during the rearing period, the light hours have reached 10h or more when the group is transferred, and there is no need to supplement it when transferring to a layer With artificial lighting, when the natural light starts to become shorter, the progress of adding artificial lighting to provide artificial lighting subsidies increases every week.
