Any construct must be thoroughly disinfected before incubation can begin.Muscovy Duck Removal In order for the incubation to start correctly, the apparatus must be warmed up immediately before laying. Eggs are stacked horizontally. On one side of the shell, a sign must be applied that is necessary for turning the eggs. Most incubators can provide temperature control, but one of the conditions under which incubation proceeds optimally is also air humidity. This indicator is very difficult to control and even more so to influence it.
The table will help to correctly adjust the temperature depending on the days of incubation.
If the air humidity can be regulated, it is better to adhere to the following schedule: 60% - 45% - 75%. Humidity values correspond to the same incubation periods as shown in the table. The steps in the incubation process include the following steps.
• At the first stage of the incubation period, the organs of the duckling are formed. Eggs should be turned twice a day at about the same time.
• At the second stage, it is important, in addition to the temperature regime, to maintain the ventilation mode. The eggs turn twice a day. In addition, it is desirable to cool them a little by spraying them with water through a spray bottle.
• In the third week, the eggs also need to be cooled. The embryo is already beginning to maintain its own temperature, and overheating is completely undesirable. However, they should not be overcooled.
• The last days are a time of waiting. It is no longer necessary to turn and cool the eggs, but it is necessary to ventilate the incubator.
Embryo Development Control
Embryo development control is a necessary measure. For this, a special device was invented - an otoscope. However, with some experience, it is possible to study the state of the embryo by viewing it through the light. Each stage of incubation has its own characteristics.
• At the end of the first stage of development (the end of the first week of incubation), the emerging network of blood vessels can be seen through light. The inside of the egg takes on a pinkish tint. If the egg is shaken, one can notice the fluctuation of the shadow of the emerging embryo. If the listed signs of development in the egg in the light or in the horoscope are not detected, the egg must be removed from the incubator.
• The next examination of the state of the embryos must be carried out at the end of the second week. At this stage, the formed embryo should be visible. In its absence, the eggs are also removed.
• The last transillumination is carried out 2 days before hatching. With normal development, the inner space of the egg will not shine through, only the air chamber is clearly visible. In this case, one can notice irregularities in the inner edge of the chamber at the place of its contact with the body of the formed duckling.
