This study was carried out to investigate the effects of hatching egg weight on hatchability, growth and survival rate in Japanese Quail. In this investigation, 2147 eggs were obtained from 8-10-weeks old quails that were reared at the Veterinary Faculty Farm of Selçuk University, Turkey and used as the material. Eggs were classified as less than 10 g, 10-11 g, 11-12 g, 12-13 g, 13-14 g, 14-15 g and greater than 15 g. When different egg weight groups were compared on hatchability of total eggs and apparent fertility, there was a statistically important difference (P< 0.001). The differences among groups for hatchability of fertile eggs and embryonic mortality were not found significant (P>0.05). Groups of 10-11 and 11-12 g were found better than other groups based on apparent fertility and hatchability of total eggs. The highest hatchability of fertile eggs and the lowest embryonic mortality were determined group of 11-12 g. The poorest hatchabilities were found in group less than 10 g. Generally, it was observed that when egg weight increases chick weight also increases, and this situation was active in following ages (P<0.05). The quails among groups of egg weight for survival rate were not found significant (P>0.05). It was concluded that eggs in the group of 10-12 g is the most suitable eggs for incubation.
