In this study, it was aimed to determine the effects of parental weight and hatching egg weight on chick quality and development in Japanese quails (Coturnix coturnix japonica). At 10 wk of age, a total of 10 wk old 75 male and 75 female parents were placed into the individual cages with 1:1 mating ratio. The eggs were incubated by pedigree. In order to determine the chick quality, weights at hatch and chick lengths were measured in seven chicks from each pair. Subsequent live weights of the birds were measured on weekly basis until six wks of age. As a result of study significant (P<0.01) positive correlations were determined between maternal weight and hatching egg weight, weight at hatch, and chick length. Correlation coefficients of these traits with maternal weight were calculated as 0.49, 0.41 and 0.42, respectively (P<0.01). In this study, it was determined that there were positive and statistically significant correlations between hatching egg weight and weekly live weights (P<0.01). As a result of study, it was concluded that incubating eggs which weigh 11.5 in grams may positively affect the subsequent performances of the offspring.
