What is the incubation period for chicken eggs?

Incubation is a complex process, the main role in which has the observance of temperature and humidity. If the temperature is high, this will significantly affect embryo development. But as a result, the brood will be small.

If the temperature is low, the mobility of the chickens will be reduced. And with deviations from the temperature, the embryos may even die. Dry air often causes premature slander, while humidity can cause a delay. Based on this, it is not difficult to understand how important incubation of eggs is considered for their proper development.

Storage time until bookmark

The total shelf life of eggs to the incubator is 6 days. Eggs, on the shell of which there is dirt, in no case can not be washed. Differences in water and embryo temperatures can cause mold and mildew. Remove dirt can be very carefully with a knife.

What influences him?

How many days in an incubator are chicken eggs? The period of incubation of chicken eggs often lasts 21 days, and it can be divided into 4 periods:

• The first period (7 days).
• The second period (from 8 to 11 days).
• The third period (from 12 days).
• The fourth period (before hatching).

Initially, important organs are formed in the embryo. The incubator should have a temperature of 38 degrees, and the humidity of the air - 60-70%. After these indicators are gradually reduced.

In the second period of incubation of chicken eggs, the beak, claws and skeleton form in the embryo. The temperature is adjusted to 37 degrees, in humidity up to 45%. Deviation up or down is not allowed.

Then the embryo becomes covered with down and acquires the stratum corneum.

Important create a temperature of 37 degrees, and humidity up to 70%.

After the first squeak, namely in the fourth period, the chickens open their eyes. They are taken and transferred to the hen. In this case, the incubation mode is considered to be over.

Development time in vivo

The period lasts from 19 to 21 days. Incubation time The time can be represented by the following table:

If something went wrong It is important to be very cautious, because Wrong conditions may result in:

• Overheating eggs. Embryos may die or be born underdeveloped. Some of them after birth may not even get stronger, while the other part will lag behind in development.
• Underheating eggs. If the eggs are not warmed, as it should, the young will not be able to stand up, and their feathers will be drooping and dirty. Such chickens can have diarrhea for a long time, they will have swelling of the neck and head.
• Low humidity. If the incubator humidity is low, the weight of the eggs may decrease. This can lead to an early brood and pecking of the shell.
• High level of importance. The weight of the eggs will be slightly reduced. On the shells you can notice the liquid. Cursed shell can be late and stretch. The hatching of young animals often has a dirty plumage, and the death of chickens can occur due to the fact that a lot of amniotic fluid remains in the egg.
• Incorrect egg rotation during the incubation period. If you do not follow the rules, chickens can be born freaks.

Conclusion

In conclusion, it is worth noting that the incubation of eggs does not last long. But during this time it is important to provide the embryos with the most comfortable conditions. This is the only way to achieve an excellent result - healthy chickens will appear from the eggs without any deviations or complications.
