The value of the temperature reading in the incubator for incubating chicken eggs

At the time of the arrival of spring, the owners of household plots want to receive young growth and renew the population of chickens, using a special device for this - an incubator. An important parameter is the temperature in the incubator for chicken eggs, since it affects the hatching results and the health of the chicks, and therefore the quality of their own eggs.

Preparatory stage

Any farmer can breed poultry, even without experience in this matter. After all, the birth of small chickens is not just a pleasant event, but also a good material support. If desired, by increasing the number of layers, you can make a profit by selling eggs.

In order for the preparatory activities to be successful, it is necessary to observe the temperature regime in the incubator for chicken eggs. The quality of the collected material and compliance with the conditions of heat, humidity, as well as the observance of ventilation and turns depends on the quality of the resulting offspring - its survival and health.

Eggs hatched in the evening and at night (from 20.00 to 8.00) are unsuitable for use in an incubator, they are unlikely to be fertilized. Better to choose eggs laid at midday or lunchtime.

The selection of chicken eggs for incubation is no different from the rules selection of goose, duck and turkey eggs.

Compliance with the regime

In order to understand the peculiarities of storing eggs in an incubator and to maintain optimal conditions, it is important to pay attention to such a parameter as the temperature in an incubator for chicken eggs. The table below contains the values ​​of the optimal parameters, contributing to the production of healthy full-fledged offspring.

The incubation process is conventionally divided into 4 stages, the duration of each of them is from 1 day to a week:

1. At the first stage (from 1 to 12 days), the future chick is formed.
2. On the second - the next 4-5 days, the formation process.
3. The third stage starts from 18 days and lasts until the baby squeaks.
4. At the last stage (20-21 days), babies actively hatch through the surface of the shell.

At each of these stages, it is very important to maintain the proper temperature parameters that will allow you to maintain the incubation regime. Depending on the stage of formation of the chick, the indicators of temperature, humidity, as well as the characteristics of ventilation change.

Before placing in trays, eggs are heated to +25 C, this is room temperature. Then the temperature regime will gradually change. The figure shows the changes in the conditions of incubation of chicken eggs by day.

First step

The indicator is +37.6 - +38 C (in the first 3-5 days it is even more - + 38.3 C, and then begins to gradually decrease) on a dry thermometer, and on a wet thermometer this indicator should be + 29 C, the size of humidity - less than 65-70%. At this stage, the eggs must be turned every couple of hours. Under natural conditions, the chicken does this by itself. Some incubator models have a built-in swivel option.

It is necessary to carry out such procedures in order to avoid the growth of the embryo to the wall, this will entail death.

At this time, the embryo needs the most comfortable "weather" conditions, since the body of the embryo develops and its complete formation takes place. You do not need to air the eggs.

Second phase

The temperature indicator in the incubator for chicken eggs decreases slightly - +37.5 C. It is necessary to turn and transfer eggs at least several times a day, the humidity indicator drops to 55%. Eggs are aired at this time 2 times a day, for 5 minutes.

Stage three

During this period, all processes take place under the auspices of air circulation, since there is an increased metabolism and gases. At this time, the entire space inside the egg is filled with an embryo, and a squeak can already be heard from the inside. The incubation temperature of chicken eggs in the incubator should be + 37.5 C. Airing is carried out 2 times a day, each time for 20 minutes.

Stage four

It is necessary to create all the conditions for the final period of chick hatching. The temperature drops slightly, to + 37.2 C, on a wet bulb temperature indicator in the incubator for chicken eggs should be 31 C. The air humidity indicator is brought to 70%.

Heat transfer should be increased, if possible, it is necessary to set ventilation to the maximum. Eggs must lie on their side, in a certain space, no turning over. The chick makes a calm monotonous sound, which indicates its normal state. Airing is carried out 2 times a day, for 5 minutes.

Chick hatching

When hatching chicks, the temperature in the incubator should maintain the same temperature values, and they should be from +37 C to + 37.5 C. After drying, hatched chicks are taken and sent to a separate box for the first feeding and further heating.

What is important to know

Measurements are taken every 2-3 hours on the surface of the egg. To measure, you must attach a mercury ball near the nougat where the embryo is located. Based on the tables, you need to compare their data with those that you received. If overheating is observed, then it is necessary to reduce the temperature indicators as soon as possible, otherwise the embryo will not survive.

Particular attention should be paid to the second half of the incubation period, since in summer the air temperature can reach + 30 C or more, then there is a great risk that the eggs will overheat. In this case, it is necessary to cool the air by blowing, but the eggs do not need to be removed from the incubator. The duration of the procedure is up to 40 minutes, until the desired parameter is reached on the surface.

A home temperature incubator for chicken eggs is an effective device that will allow you to get a number of hens in optimal and natural conditions.
