Do you know how many days of hatching an egg can produce a chicken? When does the chicken grow to start laying eggs? What is the peak period of laying eggs? do we need to care something?

A fertilized egg usually hatches the chicken after 21 days, the duck egg is 28 days, the goose egg is 30~33 days, the pigeon egg is 18 days, the pearl egg is 26 days, and the fire egg is 27~28 days. It takes these stages for a chick to go from hatching to final elimination.

Chicken raising, especially laying hens, determines the length of the egg production period. Why should limit light and limit materials before? Because, at the stage of 43~126 days, if the light is not limited, the chicken will lay eggs in advance, resulting in a shortened egg production period of 3 to 5 months, causing serious losses.

So the peak of egg production is so important, what should farmers pay attention to?

In addition to daily management, pay more attention to the condition of laying hens. Usually, in addition to packing eggs in egg packing system, clear dung, feeding, cleaning, you should also observe the status of the laying hens, see if there are sick chickens, etc. In short, pay more attention. Laying hens must ensure that nutrition is kept up.

Reduce stress and maintain environmental sanitation. High-yielding laying hens are easily frightened, resulting in less food for laying hens and lower egg production rates.

The problem to be paid attention to in raising chickens in summer: the optimum temperature for chicken adaptation is 13 to 25 degrees, and the production is customarily used for 21 to 25 degrees. In the hot summer, the chickens are fed in the cool morning.

Light is one of the necessary environmental conditions for laying hens. The intensity, time and color of light are very important for chicken activities, metabolism, growth and productivity, especially for laying hens raised in layer battery cage equipment. Reasonable control of light can improve the production capacity of laying hens and the economic benefits of farmers.

1. The effect of light on laying hens

Light stimulates the hypothalamus directly through the skull or light through the nerve pathway of the nerve lobe. After the hypothalamus is stimulated, it secretes gonadotropin-releasing hormone, which reaches the anterior pituitary through the pituitary portal system, causing follicles The secretion of stimulating hormones and ovulation hormones promote the development of follicles and then ovulation. The developing follicles produce estrogen, which promotes the development and function of the hen’s fallopian tubes. At the same time, estrogen also promotes calcium metabolism to facilitate the formation of eggshells. Ovulation hormones Causes hens to ovulate. In a closed chicken house, no matter how nature changes day and night. The laying of eggs by hens is mostly concentrated in the first 2-7 hours of artificial light.

2. Control of lighting technology

1. Lighting time. The length of lighting time is closely related to the age of sexual maturity of chickens. Too short light time during the rearing period will delay sexual maturity, and too long time will lead to early sexual maturity.

2. Light intensity. Appropriate light intensity is conducive to the normal growth and development of chickens. Excessive light can make chickens irritable and cause severe pecking, prolapse or nervousness. The sudden increase in light intensity during the laying period can significantly increase the rate of cracked eggs, soft-skinned eggs, deformed eggs, and sudden death; low illumination can accelerate the deposition of body fat, but the illumination is too low. It will reduce the chicken's feed intake, reduce drinking water, hinder growth and development, and reduce egg production.

There are four ways to control the light intensity: one is to control the intensity by increasing or decreasing the number of bulbs; the other is to adjust the intensity by changing the bulbs of different power; the third is to control the intensity by adjusting the voltage; the fourth is to control the intensity by adjusting the spacing. But no matter how you adjust, each time you turn on and turn off the lights, you must gradually change from dark to bright, from bright to dark, to give the chickens an adaptation process to prevent frightening the flock. The distance between the bulbs should be 1.5 times the height of the bulb from the ground; the distance between the lamp and the wall should be half the distance between the bulbs, and the lamps between rows should be arranged in a staggered manner to obtain a more uniform lighting effect.

3. Light color. Laying hens are more sensitive to color. Chickens have better vision under red, orange and yellow light. Under red light, it tends to be quiet, with very few pecking habit, a little later in maturity, high feed reward, and egg production slightly increased; yellow light reduces feed reward, delayed sexual maturity, increased egg weight, decreased egg production, and increased pecking ; Green light can make sexual maturity earlier and weight gain faster; blue light can reduce hen egg production.

The right temperature of the chicken house can exert greater production potential for chickens. The quality of environmental control directly affects the success of breeding. Therefore, temperature control is an important factor in feeding. The following chicken breeding equipment manufacturers explain the main points of chicken house temperature control.

In the environmental control of the layer hen chicken house, the layer chicken can obtain a higher survival rate, weight gain speed and feed remuneration in the above-mentioned suitable temperature environment. Whether the specific temperature of each brooding is appropriate or not is determined by the dynamic performance of the chicks:

When the temperature is appropriate, the chicks are evenly distributed indoors, lively, with smooth feathers, and close to the body surface. They are relatively quiet during sleep and scramble to eat.

When the temperature is too low, the chicks will show low temperature performance. The chicks will be crowded near the heat source or in a certain corner, their feathers will be fluffy, the spirit will be wilted, and they will make continuous calls. This way for a long time, it is easy to cause the chicks to catch a cold or be crushed to death. It must be heated immediately and the crowded chicks must be dispersed.

When the temperature is too high, the chicks stay away from the heat source, spread their wings and lie down, panting, and rush to drink water. There is often no water in the drinking fountain, but the fluff is wet. Over time, the physique of the chicks will be weakened, growth will be hindered, and even heat death will be caused. When the temperature is too high, the temperature should be gradually lowered, but be aware that a sudden drop in temperature can cause a cold.

Therefore, attention must be paid to the temperature control of the chicken house during the entire feeding period of the laying hens. A thermometer can be placed in an appropriate place in the house for observation, and certain measures can be taken to cool down or adjust the temperature. In the hot season, when the temperature in the chicken house is high, you can open the doors, windows and vents, turn on the fan or exhaust fan, increase the ventilation in the house, and lower the temperature in the house. When necessary, cold water can be sprayed on the ground or sprayed on the roof to cool down.

The use of poultry battery layer hen cages to raise chickens requires more attention to the living environment of the chickens in the hen house. Provide a suitable temperature environment for the chickens so that they can grow healthier.

The number of chickens per square meter of feeding area in chicken layer cages for sale is called the stocking density. The feeding and drinking position occupied by each chicken is also an indispensable condition for mastering the stocking density. If the density is too large, the chickens are crowded, the environmental humidity is increased, the feeding is uneven, the chicks are not well-developed, the disease and convulsions are susceptible, the chicks are weakened, the mortality rate increases, and the growth rate decreases.

The low density of chickens raised in wire chicken cages for sale is beneficial to the survival and growth of the chicks, but it is not conducive to heat preservation and is not economical. The density should be adjusted according to the type, variety, brooding mode, season, age, ventilation status of the chicks. Automated farming equipment cage brooding should be correspondingly increased with age, the density should be reduced by about 30% at 3 - 4 weeks of age, and by about 15% at 5-6 weeks.
