Why do you need to take care of the eggs during hatching? How many days does it take to hatch a chic

According to the egg is to calculate how high the insemination rate of the egg is, save electricity, generally the eighteenth day of mechanical incubation chickens will be out of the shell one after another, and wait until the twenty-first day has been hatched.

The incubation period is 21 days for chicks, 28 days for ducks, and 31 days for geese. Egg inspection, also known as candling, is the main and easiest way to check the incubation effect, and its effect is accurate and reliable.

Egg illumination can be used to see through the development of the embryo with the light of the egg illuminator, which can fully understand whether the embryo is developing well, so as to check whether the incubation system is correct, especially whether the temperature and humidity are suitable; If poor hatching is found, the incubation conditions or the feeding management system of the breeders can be improved immediately, so as to improve the hatchability of the eggs and the quality of the chicks.

According to the egg, you can know the fertilization rate of the egg in time and remove the infertile egg; Make full use of the incubator and increase the number of eggs hatched.

The dead embryo eggs and rotten eggs can be picked out immediately, so that there is no peculiar smell in the incubator, so as not to affect the hatching effect.

During the incubation process, according to the number of eggs and manpower, the eggs can generally be taken 1-3 times. Usually, the eggs are sampled twice for 5-6 days and 18-19 days after hatching, and 11 days after hatching in the middle. In larger hatcheries, the hatching rate of in-house eggs is not less than 85%, and the eggs are illuminated once when the embryos are transferred from the incubator to the hatcher.

Generally, the egg illuminator is used to check the development of chicken embryos during the incubation period, because the egg irrigator has a simple structure and can be self-made. It can be made of wooden boards, cardboard and thin iron sheets into a rectangle or circle, with lights installed inside, and egg-shaped holes can be dug into the sides or top of the egg illuminator. In a dimly lit place, turn on the light of the egg illuminator and place the eggs in the orifices to check them one by one.

Hatcheries mostly use portable egg illuminators, which are lightweight, easy to operate, accurate and fast. When lighting eggs, simply open the portable egg tray and aim at the eggs on the tray to check them one by one. Large hatcheries can use egg lighting tables, which can take one plate of eggs at a time, which is fast and efficient.

When lighting eggs, put the whole plate of eggs on the egg table, and install a light tube and a reflector under the table, and the light can clearly distinguish between infertile eggs, dead eggs, live embryos and embryonic development through the eggs.

The chicken hatching period is 21 days, 18 days are put on the plate, and 7 days are the eggs.

The old hen hatches the chicks, 7 days for the first time to shine the eggs, find a big and a small thick paper tube to put the eggs on the small head of the paper tube, the flashlight on the big head, the electricity must be enough flashlight to shine clearly, the fertilized egg is clear, the unfertilized egg is transparent, hatching to 11 days, the light illuminates the fertilized egg blackened to prove that the chick began to develop, the unfertilized egg is transparent to take out and eat it, the spring weather is not too warm and the chick takes 21 days -24 days to come out of the shell, the summer weather is warm and the temperature is high 19 days to start out of the shell, the temperature is higher than the shell early.

It takes about 21 days for a hen to hatch a chick, because hatching chicks requires a warmer environment, resulting in a hen may not be successful when hatching chicks, experienced hens hatch chicks with a higher success rate, some young hens because they are inexperienced, the hatching rate is lower or a chick can not hatch.

The time it takes for eggs to hatch chicks also varies depending on the temperature, and if the temperature is higher, the eggs can hatch in as little as 19 days. Because of the high temperature, the embryo develops.

Fast, but the hatched chicks may be weaker.

Generally, the chicks will all hatch in 21 days, at this time we can prepare water and food, it is best to put it next to the nest, so that the chicks and hens can eat, and we should also pay attention to frequent checks and add food in time.

How many days does it take to hatch chicks.

It generally takes 21 days to hatch chicks, 18 days to put on the plate, 7 days to shine on the eggs, affected by temperature, there may be early or delayed hatching of chicks.

Chick hatching process for 1-21 days.

1. Chick incubation for 1-4 days is the stage of internal organ development and formation.

2. Chick incubation for 5-14 days is the stage of development and formation of external organs.

3. Chick incubation for 15-19 days is the stage of embryonic growth.

4. Chick hatching for 20-21 days is the stage of chick hatching.

5. The temperature of the chicks should be kept within 1-18 days of incubation, and the relative humidity should be kept at 40%-60%; The temperature should be maintained at 19-21 days of incubation and the relative humidity should be maintained at 65%-75%.

6. During the development of the embryo, it is necessary to continuously inhale oxygen and discharge carbon dioxide and water, and pay attention to timely ventilation.

The incubation of chickens generally takes 21 days, and when hatching chicks, it is necessary to ensure that the environment is warm enough, otherwise it will be difficult to hatch the chicks. During incubation, the ambient temperature needs to be controlled and not higher than the maximum temperature, which takes 21 days. If the temperature is a little higher, it may be two days earlier, and if the temperature is low, it will take 21 days.

Whether it is artificial incubation or hen incubation, the incubation temperature of eggs is required to be about 21 degrees Celsius, from hatching to chick out of the shell normally takes 21 days, but it will also change with the outside temperature, if the temperature is higher can be less than 19 days, if the temperature is low, it will take 21 days.

The egg method is divided into three steps: head photo, second photo, and re-inspection, and one plate is taken out of one plate after inspection, and it is put back to the incubator immediately after the photo.

The head shot chicken embryo is incubated at 5-6 days, the duck embryo at 7 days, and the goose embryo at 8 days.

The purpose of the headshot: to observe the development of the embryo and detect infertile eggs, dead embryo eggs and broken eggs. At this time, the embryo with normal development, the vascular network is distinct, radially distributed, the diffusion surface accounts for 4 5 of the egg body, and there is an obvious black dot when the egg is illuminated, commonly known as "single bead".

Erzhao chicken embryos were incubated on 18 days, duck embryos on 26 days, and goose embryos on 29 days.

On the one hand, in order to detect the embryos that have been missed or wrongly detected, on the other hand, the detection accuracy can be improved and the business level can be improved.

Precautions for taking care of eggs.

It is best not to leave the eggs outside the incubator for more than 20 minutes, especially when the room temperature is low. Do not take too many eggs out of the incubator at a time, it is best to take out one tray at a time, and put it back into the incubator immediately after taking the photo. When illuminating the eggs, the action of the egg probe should be light when leaning against the embryonic egg, so as not to break the eggshell, and the eggshell is easier to break during the second illumination, so be extra careful.

It takes 21 days for eggs to hatch into chicks, and when the incubation temperature is at a temperature of incubation, hatching days are hatched; Time is the day; 21 days; When the temperature is high, the embryo develops quickly, but the chicks are weak. The optimal temperature range for the development of the chicken embryo is between.

After the eggs are laid, they must hatch within a few days before they can give birth to chicks? How many days before the eggs hatch is better.

Hello, I'm honored to give you the answer, hello, eggs are generally hatched after five days of birth, because the eggs within five days are better preserved, the nutrients in it are relatively high, more than five days later, there is dehydration, relatively speaking, the nutrients are reduced, so the eggs hatch within five days of the most socks lack of good more than five days can also be exaggerated, but relatively speaking, affected by a certain temperature of the world.

Eggs are hatched for about 21 days to hatch chicks.

The incubation temperature is time, and the incubation finger time is days; Time is the day; 21 days; When the temperature is high, the embryos develop quickly, but the chicks are weak. The optimal temperature range for the development of chicken embryos is between, but the embryos need different incubation temperatures at different stages of development.

Data development. Chick incubation is divided into natural incubation and artificial incubation. The incubation period of chickens is about 21 days, 18 days of landing, 7 days only the type of eggs are not illuminated, affected by room temperature, early or delayed hatching may occur.

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.
