Regime of incubation.

The incubation properties of eggs depend first of all upon proper feeding of poultry. If in the ration of females there are not enough nutritive materials, vitamins, microelements, mineral materials, the embryo develops poorly and it does not have enough force to get out of the egg. It dies without punching the egg-shell. They can appear as a result both of the violation of the regime and of the wrong way of turning eggs in the incubator.

These are the last days of incubation of, for example, duck and goose eggs when the highest mortality of embryos takes place. What is the reason? It is mainly the violation of the regime of incubation. If eggs are overheated, untimely breaking the egg-shell and hatching out will begin. Nestlings happen to be of small size, with navels that heal up poorly.

On the egg inner surface you can see the remnants of the egg-white that was not consumed. It is clear that the high temperature ousted a duckling or a gosling out of the egg prematurely, not allowing it to take everything he had to from the maternal material.

The major part of embryos dies in the egg from suffocation. By the end of incubation they become more sensitive to the lack of oxygen and the increased concentration of carbon dioxide. You can define that dysbolism takes place by breaking the egg-shell in the sharp end of eggs and by the wrong positioning of the embryo. Its head can be turned in the direction of the sharp end of an egg. With the insufficient gas exchange ducklings, for example, hatch out very badly.
