Advice 1: What temperature and humidity for hatching in an incubator

During incubation it is necessary to maintain the correct temperature and humidity. At non-observance thereof, the embryos can die or "hatch" the ugly chickens. Constantly taking observations of the incubation, it is necessary to eliminate defects, to take the necessary measures to preserve embryos.

Temperature and humidity


For incubation take fresh eggs, five to seven day shelf life. The shell must be smooth, without cracks, the egg is the right shape. The percentage of vyvodyaschy Chicks is high, the embryos are transferred short-term overheating or excessive cooling.

Incubation of chicken eggs takes 21 days, in a tray they are stacked vertically, set the temperature, it needs to be close to the natural conditions in which the displays of chickens, a hen – of 37.8°C. the last 3 days the temperature is lowered by 0.3 degrees. The level of humidity in the first days – 80% during the next 8 days set 70-75%, the next period is 50%. Starting from the 5th day, the eggs cool for 15 minutes once a day, on the 19th day cooling off. The temperature in the closet in the last 2 days support of 37.5 degrees, humidity 68%. Temperature and humidity is determined using thermometers. To increase the humidity put on the floor of the incubator containers with water.

Monitoring of embryo development


An effective way of monitoring the development of the embryo − candling to the candling. On day 5 you can see the blood mesh on the yolk after 10 days of incubation, clearly visible dark spot in the center of the egg. On the 19th day you can see almost the already-formed chicken.

Material several times during the incubation browsing and do a re-sort. Eggs without embryos to the light greenish color with dead embryos have black content, live embryos are highlighted pink. After rearrange the remaining eggs with embryos returned to lead the Cabinet, placed the blunt end up.

Prokleto shell, you can judge the quality of incubation. If satisfactory mode line prokleta pass around the circumference of the egg, in its widest part. When excess moisture of the chicken will shell, but won't hatch, because it is wet, sticky, eggshell adhere to it. With a lack of humidity procli observed in the middle part of the egg. Podkolodny shell dry, durable, chicken to free.

During the withdrawal of the trays should be covered with gauze to Chicks fell out over the edge. At the beginning of the withdrawal it is necessary every two hours to check the incubator and remove alcohlic chickens. The results of incubation are considered to be good if the output is 80% of the laid eggs. About the poor quality of the eggs or of the violation of the incubation, indicated by the large number of eggs with blood ring. If the eggs were laid stale for a long time was stored before incubation, the likelihood is high that the embryos die at an early stage.

Advice 2: The right hatching in the incubator

Most people in rural areas often engaged in breeding chickens. Nice, when the sector enough hens, and if the nest gets only one bird? In this case, a bail out home-made incubators. But how to select eggs and get the chickens?
 The right hatching in the incubator

 

The most favorable time for breeding bird young - April - may. From chickens bred at a later date, puberty takes place in the fall (in terms of gradually decreasing photoperiod). First of all, it affects the development: before the onset of frost, the young do not have time to get stronger, delayed molting (which will eventually affect the productivity and viability).

To achieve good vyvodyaschy and get a viable young, you need to take care of the quality of the eggs for incubation. First of all, regularly remove them from the nest, the chicken will cause dirt and spoil the eggs with their paws.

Demolished the egg is the body temperature of a bird. Its contents, cooling down, decreases in volume. The resulting free space inside the egg through the pores in the blunt end is filled with air. If the nest is dirty, dusty litter, together with the air in the egg do germs mold spores that contribute to the deterioration and destruction of embryos.

In the case when want to grow a large number of young cattle for meat, you can use the eggs of any weight, besides the obvious marriage. Round, long, or flattened laterally for insertion in the incubator are not suitable. It is better to take eggs only with a strong, clean, and smooth shell. Sometimes on its surface are visible dark spots that would suggest that stale eggs. For incubation they the soon after laying they receive and rapidly growing mold.

The incubator is better to place in a room where the temperature is constantly maintained in the range of 15-22 degrees Celsius. The incubation waste material is placed in the tray. In the apparatus to this point needs to be created all the necessary conditions: temperature, humidity, ventilation.

The entire period of incubation can be divided into three phases that differ from each other different indices.

In the initial period of incubation the eggs require more heat, poor ventilation. They need to warm up.

The average period differ somewhat lower temperature than in the primary, but stronger ventilation.

During the withdrawal the temperature was lowered even more, and the humidity and ventilation should be strengthened. Before fetching youngsters significantly reduce the humidity so that the Chicks have dried up.

For chicken eggs the initial period lasts from the first to the eleventh day, mid - set before the start of the output, and the output period of the time, I hear the peep of Chicks.

Don't forget to turn of hatching eggs in trays (especially in the early days), otherwise the embryos can stick to the shell and die. Cooling is also required. Thanks to all that conditions of incubation are approaching the natural, created by the hens.

Cool incubation eggs should start from the middle of the period. This operation can be combined with the coup eggs.

How long to cool? Bring the egg to the eyelid of the eye, and if you do not feel neither heat nor cold, is enough.

Underheating also adversely affect the viability of Chicks. It retards the development of the embryos PIP is delayed, the output is stretched. The young leaves of the eggs with a big belly, sedentary.

Incubation is troublesome, is quite complicated. It is difficult to immediately become a specialist. It all depends on your skills, care. Observe (and record), it will help you continue to make the necessary changes.
