Abstract :The effects of eggshell thickness (EST), shape index (SI) and egg weight (EW) on the hatch window (HW), hatching time (HT), gender of hatched turkey poults hatched were investigated. Total of 150 commercial Hybrid Converter breed turkey hatching eggs obtained from a turkey meat producing integration were used. The effects of these parameters on HW and HT and gender were analyzed via ANOVA-GLM. The hatching window was 656th – 688th hours, and the procedure concluded during the 688th hour of incubation. The incubation was divided into three partitions as early (656 – 667h), midterm (668 – 676h) and late hatches (677 – 688h), with the final 32 hours of incubation divided into 7 partitions (7P) from 1 to 7 as (656 – 664h, 665 – 668h, 669 – 672h, 673 – 676h, 677 – 680h, 681 – 684h and 685 – 688h). A significant relation between EST and gender was found as eggs with thicker EST female chicks hatched more than males (p˂0.05). There was no correlation between gender and EW and SI (p˃0.05). Meanwhile, the number of hatches for 7P, EST, EW and SI were not found to affect the hatch window of turkey eggs (p˃0.05).
