Резюме: One thousand two hundred parental form of the hybrid combination Label, Loman and line E at the age of 42 weeks were involved in the study. The eggs of each hybrid combination were allocated into 3 quality groups – weighting 50g, 55g and 60g. One hundred twenty eight eggs of each quality group were loaded for incubation and were used to measure their total weight, hatchability and incubation qualities. The weight of embryo-continuing eggs was measured at 7th and 18th day of the incubation. It was established that: the weight of the one day old chicks is related to eggs weight; the hatchability is related to eggs weight; if the weight of the egg is identical the weight of the male chicks is higher than that of the female chicks - the difference being more expressed in chickens hatched by largest eggs.
