Abstract: This study was carried out to investigate the effects of egg weight, storage temperature of hatching eggs, parent age and storage length during preincubation period on fertility and hatchability traits in Japanese quail. Totally 5015 eggs data obtained from Japanese quail, in factorial design trial (2x2x4x10), was analysed by General Linear Method (GLM) by using 4 way analysis of variance (10-11 and 14-15°C egg storage temperature, 3 and 6 months of parent age; <10, 10-11, 11-12, >12 g egg weights and 0-9 days egg storage length factors). Inspecting GLM results, differences among fertility averages was statistically significant for egg weight (p = 0.0001), egg storage temperature (p = 0.007) and storage length (p = 0.018) factors and was not statistically significant for parent age factor. Differences among hatchability averages was statistically significant for egg weight (p = 0.005), egg storage temperature (p = 0.0001) and was not statistically significant for storage length and parent age factors.
