Egg hatching: requirements, features, storage

Selection selection led to the fact that a lot of breeds known to date chickens have almost completely lost their maternal instinct. Because of this, there is a need for artificial cultivation of day-old chickens. Thus, an incubation egg can develop without a hen in a special incubator. Let's talk with you about what are the requirements for such eggs, how to store them correctly, etc.

Egg weight and shell quality

At present, an experienced breeder must determine the weight with an accuracy of one gram. For this, accurate electronic scales are used. It is desirable to select the largest eggs, which is due to the high content of nutrients that are necessary for the survival of the specimen. But despite this, such strict requirements are somewhat softened to the eggs of meat chickens, which is due to a lower egg production.

Egg hatching must be well protected. The most reliable barrier is the shell. An important indicator is the integrity of the structure. This not only provides protection from external influences, but also allows to realize the necessary heat and gas exchange processes. So, for incubation it is strictly forbidden to select cracked or beaten specimens of eggs. First, they quickly deteriorate, which leads to the development of bacteria. Secondly, from such an egg moisture quickly leaves, which minimizes the chances of survival of the embryo. In addition, it is not recommended to choose irregularly shaped eggs that have scratches, etc. defects.

We use an ovoscope

As noted above, the hatching egg should not have defects. But on the eye a small scratch is difficult to identify. Therefore, it is best to use the ovoscope. This is a device that glows brightly and allows you to notice the smallest defects of the egg. As a rule, immediately corrupt spoiled specimens, because it is almost impossible to get healthy offspring from them.

But it happens that some eggs are of great value, so throw them out because of a crack or a scratch is not very desirable. In this case, it makes sense to glue the crack with glue on a starch-based basis. Pay attention to marbled on the shell, which indicates that such an egg is unlikely to hatch a healthy chicken. The problem lies in the low level of development of the embryo, which does not have time to develop in 3 weeks. It is very important that the hatching egg has an air chamber that is responsible for the storage times. But this area is visible as a dark spot.

About disinfection of eggs

Almost all specimens contain a pathogenic microflora. If it is not removed, the fungus or bacterium can penetrate and damage the embryo. To prevent this, it is necessary to disinfect the surface. If we talk about industrial scales, then we use formaldehyde vapor. Take the enamelware and pour into it about 30 ml of formalin and water. Further, the same amount of sodium permanganate is added. All this is mixed and put in a special chamber, where already there are prepared eggs. As a result of the chemical reaction, steam is released, which destroys all pathogens. Such an amount of the mixture is sufficient to process the chamber with an area of 1 square meter. The disinfection procedure should proceed at a constant temperature of 37 degrees Celsius for half an hour. Of course, besides this, the broiler hatching egg can be treated with 1% iodine solution, 3% chlorine solution, etc. Let's go further.

Hatching Eggs: Storage Rules

It is extremely important to observe the optimum temperature and humidity. According to the research, it is best to maintain a temperature of 18 degrees Celsius, since it has the highest hatchability of young animals. Relative humidity in this case should be at least 85%. It is desirable that between the demolition of the egg and its laying did not take much time. This is due to the fact that it begins to age and at the same time lose weight. The excretion of chickens is somewhat worse, in part because water is lost from the protein. Admissible weight loss - no more than 0.2% of the total mass. Proceeding from the above, it should be said that the hatching egg of the broiler, quail and other birds should be stored outside the incubator for no more than 6 days. After the expiration of the time the hatchability of the offspring is greatly reduced. Consequently, the productivity of the economy will also deteriorate, so do not forget about it.

On how to lay a chicken hatching egg

Most experts say that it is necessary to lay eggs directly in the incubator in the evening. This is due to the fact that in the morning you can choose dried, that is, unsuitable chickens. But despite this, you can perform this procedure when you are comfortable. It is extremely important to choose the same mass of eggs. This is due to the fact that larger eggs should be in the incubator more than average and small. In this case, before the bookmark, you must take into account the temperature difference. If storage was carried out in a cold room, you need to put the eggs in a warmer room, which will avoid large evaporation of moisture. The bookmark should be placed in an upright position, and if the tray is not full, then the eggs are fastened with a metal strip. This is to ensure that the eggs remain in place while turning.


Do not forget that a certain microclimate must be observed in the incubator . This humidity, which should be at least 75%, as well as good air supply. According to statistics, one chicken egg consumes about 4 liters of oxygen and emits 3.5 liters of carbon dioxide to the environment. That is why the intake and exhaust ventilation is an obligatory attribute. This requires a hatching egg, quail, goose and other birds. Do not forget that a wet thermometer should show a temperature of at least 29 degrees, and a dry one - about 37. Somewhere after 6 days of incubation, you can observe the network of blood vessels. The embryo itself is not yet visible. You can notice it on the 11th day of development. Well, here, in principle, and all that can be said about how to store eggs for further incubation.
