According to the biological constraints (short period of reproduction and exceptional variability of hatching in relation to the quality and color of the eggshell), scientific knowledge about biological mechanisms and the biological potential of pheasant embryos is essential, in order to define the optimal conditions of incubation and increased hatching of pheasants, their viability and meat quality, and therefore the economic validity of farm production of pheasant game. Role of morphological characteristics of pheasant eggs (egg weight, color of eggshells, calcification of eggshell) on incubation, and particularly on the postnatal development and production characteristics has not been sufficiently determinated. In order to obtain answers to questions and current biological limitations, this paper presents the examinations of distribution, weight, conception, hatching and vitality of pheasants hatched from eggs which were visually classified into 4 groups (A/dark brown; B/light brown; C/brown-green and D/blue-green) and incubated under standard production conditions. Based on the monitoring and analysis of these parameters, it can be concluded that based on the criteria of the color of eggshells it can be expected indirect reflections on some of the production characteristics: the quality of the eggshell, conception of eggs and hatching.
