How to hatch eggs artificially?

One, put the eggs in a cotton-fixed, insulated container (joint venture) and insert a thermometer, then find a heat source with a slightly fixed temperature. The most important thing is to make the thermometer show the following temperatures

Embryonic age ? Temperature

1-6 days 38.5-38.0°C

7-12 days ? 38.2-37.8℃

13-18 days 37.8-37.6℃

19-21 days 37.5-36.9℃

Two, precautions

1, every day, you have to turn the eggs 6-8 times. This is done to change the orientation of the embryo, prevent adhesion and promote amniotic membrane movement. Egg turning angle to horizontal position forward and backward 15 degrees each is appropriate. Generally to 18 days to stop turning eggs.

2, must ensure that the temperature is close to the standard temperature above, appropriate humidity can make the embryo in the early stage of incubation heat well; out of the chick appropriate humidity can make the shell texture brittle. Specifically, you can just put a few extra cups of water near the egg incubator.

3, the selection of eggs, to choose the shape of the regular, and the shell surface is too rough, the shell is too hard, as well as double yolk eggs are not hatchable. The weight of the egg should be 55-65 grams.

Artificial Incubation Precautions

1, choose a good breeding egg for incubation.

First of all, we should pay attention to the source of the breeding eggs, high-yield, high-quality and disease-free breeding eggs; secondly, we should choose the eggs with clean surface, oval shape, egg weight 50-60 grams, shell thickness uniformity, color positive, no broken breeding eggs.

Deformed eggs such as long eggs, flat eggs, prototype eggs, oversized eggs, drum eggs, sandy eggs, cracked eggs and eggs with light inspection of the egg internal sticky shell, loose yolk, yolk fluidity, air bubbles in the egg, gas chamber bias, gas chamber flow, the gas chamber in the middle or the small head of the egg can not be selected for hatching eggs.

2, hatching eggs in 10 ℃ -15 ℃ temperature

Store not more than 3 days.

The longer it is kept, the worse the hatching effect will be. If kept at 21℃-25℃, they should not be kept for more than 7 days at most.

3, good sterilization of breeding eggs.

Breeding eggs output, by feces, dust and other pollution, eggshells above a large number of bacteria, not only affecting the hatching eggs, and contamination of the incubator and utensils, spreading a variety of diseases. Before the eggs are hatched, they must be sterilized once.

4, strictly grasp the incubation temperature.

The eggs should be preheated 12 hours before hatching. The method is to put the eggs in the egg tray with the big head facing up, and put them in the 22℃-25℃ environment to preheat.

The best time for egg laying is around 4 o'clock in the afternoon, which enables the peak emergence time to occur during the day for easy work. The incubation temperature is 37.8℃ for the beginning to 18 days and 37.5℃-37.3℃ for 19-21 (chick emergence) days. If the temperature is too high, the chicken embryos die or increase the number of lame chickens and deformed chickens; if the temperature is lower than 24 ℃, the embryos will die mostly or completely after 30 hours.

5, strictly grasp the incubation humidity.

Breeding eggs incubation 1-18 days when the need for relative humidity of 50% -60%, 19-21 days the need for relative humidity of 60% -70%. Seed eggs incubation humidity is appropriate, can make the embryo heat evenly; in the late incubation, is conducive to the embryo heat dissipation; out of the chick when the humidity is higher, the chick is easy to break the shell.　

6, ventilation during incubation.

Embryonic development needs to inhale oxygen and expel carbon dioxide gas, especially in the late incubation, more oxygen is needed. Insufficient supply of oxygen, chicks will smother the shell. Ventilation is to provide oxygen in fresh air, and can ensure uniform temperature and humidity in the incubator, and exclude dirty gas.　

7, regular egg turning.

Long time without turning the eggs, the embryo is easy to adhere to the eggshell membrane, affecting embryonic development. The purpose of egg turning is to change the position of the embryo, to prevent the embryo from sticking to the eggshell membrane, and to increase the movement of the embryo to promote the blood circulation of the embryo.

1-10 days: 1 time/hour, 11-16 days: 1 time/2 hours, when incubation reaches 18 days, stop turning eggs. Egg turning is to make the whole egg rack tilted 45 degrees forward or backward, turn the eggs gently, steadily and slowly.

8, according to the egg, timely temperature regulation. Eggs hatch to the 5th day for headlight to see the eggs. Before looking at the embryo, first randomly take 30 eggs and put them flat for 5 minutes, so that the embryo floats, when you look at the egg can be seen. Normal development of the embryo can see obvious black eyes, if 70% of the eyes, indicating that the temperature is appropriate, a slight cooling of about 0.2 ℃ or maintain to 10-11 days and then drop.

9, change the disk on time.

The embryonic eggs from the incubator hatching tray to the chick plate is commonly known as changing the plate. Eggs incubated to 18 days when the plate change, 19 days when the chick's mouth has been into the air chamber, began to peck the shell, 20 days one after another out of the shell, 21 days out of the end of the shell.

Because the temperature in the incubator cannot be absolutely uniform, the development rate of the embryo also has some differences. In order to regulate the speed of embryo development, when changing plates, the original embryonic eggs in the upper layer should be changed to the lower layer of the chick, the original embryonic eggs in the lower layer should be changed to the upper layer of the chick, the original embryonic eggs on both sides of the egg should be adjusted to the middle of the chick, the original embryonic eggs in the middle of the egg should be adjusted to the two sides of the chick. The proverb says "21 days is not bad eggs".

10, out of the shell seedlings.

The chicks should be vaccinated with Malik vaccine within 24 hours after they come out of the shell.
