The article discusses about aspects that are necessary for taking into consideration before the incubation of chicken eggs. The result of the incubation process is a healthy chicken, which not only survives the incubation period, but can also develop into a full-fledged chicken that can satisfy human nutritional needs in meat and eggs, as well as serve as a link in the cultivation of new generations of poultry. A detailed technique, aimed at dividing the total mass of eggs into separate categories according to external features (egg shape, shell quality, egg weight, geometric parameters, color) and internal composition (protein, yolk and the shells, their proportion and density of the egg), has been developed for the diagnosis of eggs` condition and potential as part of the incubation. In addition, the aspect of the influence of electromagnetic fields on living organisms, both at the level of unicellular and multicellular organisms cause a considerable interest. On the one hand, the increased effect of the EMF can have a negative effect, since it provokes the development of a stress condition in the organism (up to death), on the other hand, it can be used to improve the development of poultry.
