How do commercial chicks hatch? How do you hatch chicks and what materials do you need?

1) Temperature: Temperature is an important condition for embryonic development. The embryo can still develop at a temperature of 32-40 degrees.

Shi Wen should be high in the front, flat in the middle, and low in the back. Full and full incubation, 1-7 days for the early stage, with temperature, 8-14 days for the middle stage, with temperature, 15-21 days for the late stage, with temperature. If multiple batches of eggs in the machine are hatched at the same time, the temperature can be used at a constant temperature of 15-21 days.

If multiple batches of eggs are hatched at the same time, the temperature can be kept constant. At 21 days, the temperature can be appropriately increased to facilitate the smooth hatching of chicks. Effect of high temperature on embryonic development:

High temperatures shorten the incubation period and increase mortality. The embryo will die in 2-3 hours at 42 degrees Celsius: Effect of low temperature on embryonic development:

Low temperatures can prolong incubation and increase mortality. In the low temperature below 36 degrees, after more than one day, the embryo will be underdeveloped, and most of them will die in the shell before coming out of the shell. (2) Humidity:

The development of the embryo has a wide range of adaptation to humidity. Generally between 50 -70, 1-7 days for the first period, the relative humidity should be 60. 8-17 days for the middle period, the relative humidity should be 50, and in the late 18-21 days, the relative humidity should be 70.

This is because amniotic fluid is produced in the early stage, urine is excreted in the middle stage, and it is conducive to shelling in the later stage. Effect of high humidity on embryonic development: affecting the removal of allantoic night, resulting in excessive hair of young chicks, big belly, bulky and sluggish, Effect of low humidity on embryonic development:

The water in the egg evaporates too much, resulting in a small body of the chick with short hair. (3) Ventilation: Good ventilation conditions can supply sufficient oxygen to the embryo and discharge carbon dioxide at the same time to ensure the gas metabolism and physiological function of the embryo.

If ventilation is poor, fetal malposition and malformed embryos will occur. Or even death. In the early stage of incubation, there is less oxygen due to low metabolism of substances

prevent carbon dioxide poisoning; The specific gravity of sulphur dioxide is less than that of air, so he left a small hole in the roof of the hatchery in the upper part of the hatchery chamber to prevent poisoning. (4) Egg turning: The main function of egg turning is to avoid adhesion between the embryo and the egg membrane.

The yolk is lighter than the egg white, and the embryo is lighter than the yolk. The embryo is often in contact with the egg membrane, and the position of the egg is changed when the egg is turned, and the contact point between the embryo and the egg membrane is also changed, so the adhesion between the embryo and the egg membrane is avoided. Number of egg turns:

Turning the eggs once every hour and a half. After 17 days, the eggs do not need to be turned over and the eggs are moved to the hatch area. (5) Cool eggs:

The function of cold eggs is mainly to dissipate excess physiological heat in the egg to provide sufficient oxygen to the embryo and prevent the occurrence of overtemperature accidents and the suffocation of the embryo due to hypoxia. There is no need to cool the eggs for 1 to 7 days, and once a day for 8 to 12 days, for 15 minutes each time. Cool twice a day for 13 to 17 days, for 20 minutes each time.

From the 18th to the 21st, cool every 4 to 6 hours, and cool for 15 to 20 minutes each time. The method of chilling the egg; Open the front door and turn the cold egg in the middle once, and the cold egg can also be combined with the adjustment plate.

Use a computer to control the temperature of the incubator.

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 should not exceed three layers, and a thermometer should be placed on top of the egg.

The top of the box is tightly covered with a quilt to 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.

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.

Chicks hatch out can stay in the incubator, chicks out of the shell 18-36 hours before leaving the incubator, after leaving the incubator should pay attention to keep the chicks in the environment of 18-24. It takes about 21 days to hatch chicks, and the incubation time will be affected by the temperature, and there will be early or delayed phenomena. When hatching chicks, it is necessary to ensure that the surrounding air is circulated, if the ventilation is poor, there will be a severe lack of oxygen in the incubator.

It is best to drink water within 12 24 hours after the chicks are hatched, and not more than 36 hours, and before eating. Specifically, it should be transported to the brooding house, a little rest should be allowed to drink water in time, especially after long-distance transportation, the body water loss is more, timely drinking water can supplement the chicks' physiological need for water, help to promote appetite and digestion and absorption of feed.

How are newborn chicks fed? It's important to lay a good foundation.

Newborn chicks have a strong imitation, the first drink can be artificially assisted to make the chicks learn to drink water, the drinker is evenly placed between the troughs, and ensure that each chick has a 1 2 cm slot. The temperature of drinking water should be close to the temperature of the house, keep it at about 20, and it is best to add an appropriate amount of penicillin (2000 units), vitamin C (mg) and 5% 8% glucose or sugar to the drinking water. In the first few days, potassium permanganate can also be added to drinking water, which can disinfect drinking water, clean the gastrointestinal tract and promote meconium discharge, which helps to enhance the physique of chicks and improve the survival rate of chicks.

In addition, it is necessary to drink water freely and keep it clean and hygienic. With the increase of age, adjust the height of the drinker in time so that the edge of the drinker is close to the back of the chicken.

How are newborn chicks fed? It's important to lay a good foundation.

Timely feeding helps the chick to fully absorb the yolk and excrete the meconium, which is beneficial to the early growth of the chick. The opening time is after boiling water or at the same time. At the time of feeding, chicks before 5 days of age can spread the feed on thick paper or plastic sheeting with a dark background, or they can be placed in a shallow dish with a beam and increased lighting to induce chicks to peck freely.

After 5 days of age, feed troughs can be switched to feeding, and as the chickens grow, keep the height of the trough edge level with the back of the chicken, so that each chicken has a 2 4 cm long trough. Chicks can directly use full-price ingredients to eat, less to add to the diligent and fast, and let the chickens eat freely.

1. Preparation before brooding: before entering the brooding house, the brooding house should be thoroughly cleaned, the trough, sink and other utensils should be cleaned, and strict disinfection should be carried out. Before entering the hatch, the brooding house should be preheated in advance, especially in late autumn, winter and early spring, it is necessary to make a fire 3 days in advance, so that the walls, floors and facilities are heated through, so that the temperature in the house is relatively stable and easy to control.

2. Temperature and humidity: temperature is one of the key factors in the success or failure of brooding, and providing a suitable temperature can effectively improve the survival rate of chicks. Due to the imperfect thermoregulation function of chicks, chicks are very sensitive to temperature, the temperature is too low, the chicks are easy to squeeze and die, the temperature is too high, the water in the chicks is easy to evaporate, resulting in dehydration of chicks, affecting the growth of chicks.

Generally, the first week of the chick house is 32 35, and then it will drop 2 3 per week, and the cooling range can not be too large, and it will be dewarmed when it drops to 18 20. Too much humidity is not conducive to the growth and development of chicks. Humidity is generally 65% to 70% at 10 days of age, and remains at 55% to 65% after 10 days of age.

3. Feeding. Drinking water before chicks start eating, at the age of 1 7 days, glucose and electrolytic multivitamins can be added to drinking water to facilitate the absorption of yolk body of chicks. Tap water can be drunk after 1 week of age, and the water should be clean and not cut off.

Disinfect the drinking fountain with potassium permanganate once a day. Chicks generally start feeding 24 to 26 hours after hatching, and the starting feed can be used millet, crushed corn and other feeds, and gradually changed to compound feed after 3 days of age. The number of feedings, generally 1 45 days old, 5 6 times a day; After 46 days of age, feed 4 to 5 times.

It is not advisable to feed too much each time, and it is advisable to feed less frequently, and it is advisable to feed eighty percent full.

After the chicks are bought, they should be raised from the following aspects: 1. Keep warm. After the purchase, the chicks will be raised in an environment of 32 °C, if the number is very small, look at the kang spread on the paper shell, surrounded by wooden boards, covered with plastic sheeting, to create a small environment of heat preservation.

The temperature is lowered to 30°C for the second week and 2°C per week thereafter until it is reduced to room temperature. 2. Drink water. If you want to feed the newly purchased chicks, you should drink warm boiled water (30 °C), and put some glucose or gentamicin injection in the water, which can increase the physical strength of the chicks, eliminate bacteria in the digestive tract, and increase the speed of meconium excretion.

Chicks should drink warm boiled water in the first week, and after the second week, the water does not need to be boiled, and they can drink tap water. Drinking water should be done with a special drinking fountain for chicks, or you can fill a canned bottle with water and buckle it upside down on a shallow plate, and tiptoe up with a toothpick under the bottle. 3. Feeding.

The chicks can be fed after drinking the water, and the chick compound feed prepared in advance is placed on a shallow dish or plastic sheet, so that the chicks can eat freely, and less frequent addition. 4. Density, 25 birds per square meter at the beginning, 20 birds per square meter in the second week, and then gradually reduce the feeding density with the increase of age. 5. It is necessary to do a good job in the hygiene of the chicken house, and do a good job in disinfection, epidemic prevention, deworming and other work.

Generally 6 weeks, the chicks can be dewarmed. Move to outdoor rearing.
