Abstract: In order to determine characteristics for hatching of two quail strains 1500 eggs of Japanese quail (Cotunix Japanese) and 1200 eggs of Range quail (Coturnix ypsilophorus) were randomly selected from breeder quails (8-16 weeks of ages). The eggs were incubated in artificial incubation in six hatches. Fertility and hatchability of fertile eggs were 74.5±7.9 and 72.46±10.73, respectively. Egg, shell and chicken weights were 10.68±1.01, 0.82±0.08 and 7.547plusmn;0.84, respectively. Chicken and shell weights were significantly affected by strain (p<0.01), while there was no strain effects for fertility, infertility, egg weights (p>0.05). Hatchability (fertile and total eggs), egg weights, chicken weights, shell weights were significantly different in six hatches, while there were no significant differences for fertility and infertility of eggs.
