In this study, the effects of flock age, storage time and the time elapsed in the early stages ofincubation on the relationships between egg weight and thick albumen height in hatching Japanesequail eggs were investigated. Five different levels of flock age (8, 12, 18, 25 and 30 weeks); 4different levels of storage period (0, 1, 4 and 7 days) and 5 different levels of elapsed time in theearly stages of incubation (0, 6, 24, 30 and 48 hours) were considered. The correlations between eggweight and thick albumen height in all flock ages were found to be significant (P<0.05). Theregression coefficients between thick albumen height and egg weight were 0.115, 0.082, 0.054,0.085 and 0.061 mm/g at the respective age periods; and the R2 values were found to be 4.43, 2.11,1.85, 2.76, and 2.42 %, respectively. The correlation between egg weight and albumen height wasonly found to be significant in eggs stored for 4 days. The regression coefficient was determined as0.061 mm/g, and the R2 value as 1.77 %. The correlations between egg weight and albumen heightwhich were measured at 0 and 6 hours of incubation were only found to be significant. At theseelapsed times, the regression coefficients between albumen height and egg weight were determinedas 0.0808 and 0.0809 mm/g, and R2 values were determined as 2.44 and 3.03%, respectively. Thereis no fixed relationship between albumen height and egg weight, which is applicable in all cases,such as different flock ages and storage times.
