Duckling in an incubator has several advantages. The most important – you can always get the required number of chicks. Duck eggs because of the large size, shell thickness and fat content have their nuances for breeding in the incubator.
First of all, you need to maintain a certain temperature regime. In addition, they need a higher level of humidity and special attention. The period of incubation of duck eggs takes 26-28 days.
The percentage of hatchability and health of future offspring depends on the nutrition of the ducks. To obtain quality eggs, the diet of the bird requires the inclusion of minerals and trace elements. In this case, you can give them chalk, shells, limestone. It is also necessary to add greens, grass, vegetables and corn to feed. Ducks should spend more time in the sun and fresh air. The resulting vitamins contribute to resistance to diseases and improve the blood circulation of future chicks.
The main criterion for selection is the freshness of eggs. They can be collected for 7 days and kept in a dry place at a temperature of 8-13 ° C. Muscovite eggs can be stored for up to 15 days. The appearance of eggs should also be carefully studied, by rejecting the non-standard shape, the shell with cracks, accretions and any damages.
After the eggs are collected, they are laid in a pre-prepared incubator. The trays are washed and dried. To humidify the air in the apparatus, containers with water are placed, the necessary thermal regime is set. There are different models of incubators. Some devices automatically set the parameters of humidity, air circulation, temperature, as well as turning the eggs. The more automated functions in it, the less time will be expended for the breeding process. For ducks, you need to set the air level to 770 ml.
The first 8 days of eggs should be in the incubator at a temperature of 37.8-38.3 ° C and an air humidity of 58-62%. These days, the embryo forms internal organs, including the heart. Change the position of eggs should be 4 times a day.
From the eighth day, the temperature is reduced to 37.8 ° C. During this period, the skeleton of the future chick is formed. Since duck eggs contain a lot of fat and little water, during the incubation produces an excessive amount of heat. This can lead to the death of the embryo. To prevent this, eggs need to be cooled periodically. It is not necessary to get them out of the incubator. It is enough to turn off the device and open the doors for 15-20 minutes. Next, the eggs are sprinkled with water from the sprinkler. You can add a little bit of potassium permanganate into it. Do this 2 times a day and do not forget to turn the eggs 4-6 times. On the eighth day, the first X-ray is carried out in order to reveal the dead embryos.
The third stage is characterized by an increase in heat transfer. The temperature in the egg rises to 40-42 degrees. The nestling is almost completely formed. During this period, a second X-ray is performed and eggs are taken by weight. At the fourth stage, the ducklings are taken out.
From the 26th day, the egg revolution must be stopped. When piquing starts, humidity and ventilation should be increased to soften the shell a little and help the chicks to hatch. On day 27 the ducklings begin to be excreted. This process lasts up to 24 hours and ends usually on day 29.
It is necessary to wait, when all ducklings completely dry and after that to transfer them in a box where the first 10 days maintain a temperature of 26-28 degrees, from 11 to 20 day it can be reduced to 22-26 degrees. Normal chicks at birth have a weight of 45-70 g, they are mobile and well stand on the legs.
Self-breeding ducks provides an opportunity to get healthy birds, as well as confidence in their breed. Observance of all conditions of incubation greatly contributes to the appearance of a full brood.
