Methods of artificial incubation of chicks, techniques and methods of hatching chicks

Techniques and methods for hatching chicks:

1. Egg selection and disinfection.

1. Eggs need to be fertilized eggs, and it is advisable to choose eggs that are stored within 7 days, and the longer the storage time, the lower the hatching rate.

2. After selecting the eggs, disinfect the incubator first, and then put the eggs on the egg tray for disinfection, and the disinfection can generally be fumigated with potassium permanganate and formaldehyde in a ratio of 1:2, note: In order to enhance the disinfection effect, the incubator can be heated to more than 20 before disinfection.

2. Temperature and humidity.

1. Temperature. 1) Constant temperature incubation method.

The temperature is always controlled.

2) Variable temperature incubation method.

The incubation principle is "high in the front, flat in the middle, and low in the back", that is, the temperature of 1-6 days, the temperature of 4-16 days, and the temperature of 17-20 days.

3) Attention. When the room temperature is below 15, the incubation temperature should be set according to the actual temperature in the incubation room.

2. Humidity. The principle of incubation humidity is "high in the front, flat in the middle, and higher in the back", that is, the humidity is 60-65% for 1-7 days, 50-55% for 8-18 days, and 65-70% for 19-21 days.

3. Ventilation and egg turning.

1. Ventilation. 1) The carbon dioxide content in the air around the embryo egg should not be exceeded, if the carbon dioxide content exceeds 1%, it will increase the mortality rate.

2) The incubator will generally set its own ventilation program when leaving the factory, usually every hour, the ventilation fan will automatically ventilate for 25 seconds to provide sufficient oxygen for the embryos.

2. Turn the eggs. In general, in the 21 days of incubation, it is usually only necessary to turn the eggs in the first 1-18 days, every 2 hours, and the angle of turning the eggs is 45°.

Fourth, dry the eggs according to the eggs.

1. Dry eggs. 1) Egg drying is generally carried out at the same time as egg turning, and if the incubation conditions are suitable, there is generally no need to dry eggs.

2) If in summer, the temperature is higher than 30 and the eggs are hatched to the middle stage, they generate a lot of body heat, and the temperature in the incubator is high, it is generally necessary to dry the eggs.

2. Shine on the eggs. 1) Breeding eggs need to be illuminated 3 times during incubation, if they are white eggs, they generally need to be photographed for the first time on the 5th day, brown eggs are selected on the 7th day, and infertile eggs, blood ring eggs and dead sperm eggs are picked out in time.

2) The second choice is on the 11th day and the third choice is on the 18th day.

Fifth, hatching. 1. When the eggs hatch to 18 days, they will start pecking and need to move the eggs to the hatching basket so that they can hatch in the basket.

2. When most of the chicks have come out of the shell, but there are a few eggs that have not come out of the shell (there is a cry in the egg), artificial midwifery is required. You can first knock the eggshell with your hands, if you hear the sound of emptiness, it means that the blood vessels have dried up, and when you are midworking, you can pull the chick's head out and let it slowly come out of the shell.

3. If you encounter adhesion between the chick and the egg membrane, you can soak it with warm water first, and then gently peel it off.

1. Choose eggs for hatching. First of all, we should pay attention to the ** of breeding eggs, high-yielding, high-quality disease-free eggs; Secondly, it is necessary to choose eggs with a clean surface, oval shape, egg weight of 50 60 grams, uniform shell thickness, positive color, and no damage.

2. Hatching eggs should not be stored at a temperature of 10 -15 for more than 3 days. The longer it is stored, the worse the incubation effect. If it is stored in a scattered environment of 21 25, it should not exceed 7 days at most.

3. Do a good job of disinfection of eggs. After the eggs are laid, they are contaminated by feces, dust, etc., and there are a large number of bacteria on the eggshells, which not only affect the hatching of the eggs, but also contaminate the incubator and utensils, and spread various diseases. Eggs must be sterilized once before they are set.

4. Strictly grasp the incubation temperature. Eggs are pre-warmed 12 hours before set. The method is to stack the eggs in the egg tray with their heads facing up and preheat them under the 22-25 ambient denier.

Choose a carton (or wooden box) to hatch chicks, 30-60 eggs can be hatched at a time, simple and easy, every family can hatch, and the method of hatching flowers is; Choose a carton (or wooden box) according to the number of hatched eggs, put the bottom of the box and the four walls with paper, and spread half an inch of cotton on the bottom of the box and around it. Place the selected eggs in the box. Generally, it can not exceed three layers, put a thermometer on the egg, and cover the box with a quilt to keep the temperature in the box at 38-39 degrees, and it is best to turn the eggs every 6-8 hours to keep the temperature uniform.

When incubating to 19 days, put the head of the egg upward, surround it with cotton, cool the egg every 3 hours or so, 1-2 minutes each time, and the chicks will come out after 1-2 days.

In addition, when hatching chicks, pay attention to the selection of eggs: oval eggs out of hens, nearly round eggs out of roosters. The summary of Xingye incubator breeding engineers for many years is for your reference and experiment only.

How to hatch chicks at home by yourself!!

Step 1: Take a large box first, and then take a small box, the small box is surrounded by cotton, under the cotton is a hot water bottle, a total of four on one side, and then put the eggs soaked in disinfectant water into the small box, and the nest of the chicks is set up. The temperature on the first day was maintained for 7 days, and the eggs were turned every 2 hours.

On the 8th day, the temperature dropped and the egg turning time was changed to 3 to 5 hours. That night I put 6 eggs in the egg lamp and saw that 4 of them were red and had vague blood vessels, that is, there were chicks, and the yellow ones were infertile eggs. So I threw the gotten eggs.

Later, I took a photo every few days, and I saw that the red blood vessels gradually increased, and at the same time, I could see a small black dot floating in the egg, which was the embryo of a chicken. Chicks emerge after 1-2 days.

In addition, when hatching chicks, pay attention to the selection of eggs: oval eggs out of hens, nearly round eggs out of roosters.
