In this paper are analyzed productive and reproductive results (eggs, foods and broiler chicken production) of heavy hybrid of poultry Hubbard Flex on the farm Meterize - Oplenacka Topola, Serbia, with a special attention on the influence of ages (operation period) of family flock on the lay magnitude and percent of incubates chicks. Exploitation period of family flock was 34 weeks, from 24th to 61th week of age. Productive period was long enough for calculating of phenotypic correlations. According the results we can conclude that productive results of family flock of heavy hybrid in the most of productive and reproductive attribute accomplished the satisfactory results. This statement is confirmed by calculated phenotypic correlation coefficient and level of a statistical significance between ages and lay magnitude and percent of incubates chicks.
