Popis: This study was designed to compare of laying performance, egg quality and bone characteristics of commercial and Türk laying hen genotypes kept in free-range system. A total of 720 laying hens (Atabey, Lohmann White, Atak-S, Lohmann Brown; n=180 hens/genotype) were used in the experiment. Production performance was determined as the mean of egg production, egg weight, and FCR value between 54 and 66 weeks of age. Egg quality parameters and bone characteristics of tibia and femur were measured at 66 weeks of age. The mean value of egg production was found to be higher in Lohmann Brown and Lohmann White genotypes compared to Atak-S and Atabey genotypes between 54 and 66 weeks of age (P
