Indigenous methods of incubating chicks, techniques and methods of hatching chicks

When hatching chicks in the soil method, choose a cardboard box with half an inch of cotton at the bottom of the box and around it, put in the eggs and put a thermometer to cover it tightly with a quilt, turn the eggs every 6-8 hours, and put the head of the egg up when it hatches to 19 days and wait for the chicks to hatch.

1. Choose a carton according to the number of hatched eggs. Spread half an inch of cotton at the bottom and around the box. Put the selected eggs into the box, generally not more than three layers, otherwise the hatching effect will be affected. A thermometer is placed on top of the egg to measure the temperature.

2. The top of the box is covered with a quilt to keep the temperature in the box at 38-39 degrees, so that the eggs are in a warm environment. The top of the box is tightly covered with a quilt to keep the temperature inside the box at 38-39 degrees, so that the eggs are in a warm environment. It is best to carefully turn the eggs every 6-8 hours to keep the temperature even.

3. When incubating to 19 days, put the head of the egg upward. Take care of the handling. Cool the eggs every 3 hours or so, 1-2 minutes each time. Wait patiently, and the chicks will come out after 1-2 days.

Chicken embryo in the process of development, must carry out gas exchange, at this time if the ventilation is poor, it causes serious hypoxia in the incubator, even if the chick breathing volume out of the shell is increased by 2-3 times, still can not meet its need for oxygen, the result inhibits the middle of cell metabolism, so that acidic substances accumulate in the body, the partial pressure of carbon dioxide in the tissue increases and metabolic respiratory acidosis occurs, resulting in a decrease in stroke volume, myocardial hypoxia, necrosis, cardiac disorder and sudden arrest.

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.

The techniques and methods for hatching chicks are as follows:Chick incubation is divided into natural incubation and artificial incubation. The incubation period of chickens is about 21 days, 18 days of putting on the plate, 7 days of eggs, generally to room temperature, there may be early or delayed hatching.

Natural incubation, with hens hatching eggs, can save labor and provide the right temperature and humidity, but is not suitable for large-scale incubation of eggs. Proper temperature and humidity control can have a direct impact on egg hatchability. Therefore, the selection of appropriate incubation technology and manual control of the incubation environment can improve the hatchability of eggs.

Factors influencing incubationDuring the development of the chicken embryo, gas exchange must be carried out, especially after the 19th day of incubation (12 hours earlier in summer), the embryo begins to breathe in the lungs, the oxygen demand gradually increases, and the carbon dioxide emission gradually increases.

At this time, if the ventilation is poor, it causes serious hypoxia in the incubator, even if the chick breathing volume is increased by 2-3 times, it still can not meet its need for oxygen, and the result inhibits the intermediate of cell metabolism, so that acidic substances accumulate in the body, and the partial pressure of carbon dioxide in the tissue increases and metabolic respiratory acidosis occurs, resulting in a decrease in stroke volume, myocardial hypoxia, necrosis, cardiac disorder and beating.

The simplest, with a carton (or wooden box) can hatch chicks, can hatch 30-60 eggs at a time, simple and easy, every family can hatch.

Flower hatching method: choose a carton (or wooden box) according to the number of eggs incubated, use paper at the bottom of the box and the four walls, and spread half an inch thick cotton or hay on the bottom of the box and around it. Place the selected eggs in the box.

Generally, it should not exceed three layers, put a thermometer on top of the egg, and cover the box tightly with a quilt.

Keep the temperature inside the box at 38-39 degrees, and it is best to turn the eggs every 6-8 hours to keep the temperature even. 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.

Hello! To hatch chicks needs to have a rooster, and a hen has a desire to hatch chicks. Get some eggs and put them in the coop, and after a while the chicks will hatch.
