Özet: This experiment was carried out to determine the effects of specific gravity and breeder age on egg weight loss during incubation, and on the hatchability and embryonic mortality of broiler breeders. The eggs from Ross commercial broiler breeder flocks were collected (age 34 and 59 weeks). The eggs were divided according to specific gravity into two groups: thin shelled, 1.080. The effects of specific gravity and breeder age on egg weight loss, embryonic mortality and hatchability were significant (P
