Abstract :This investigation was carried out to determine the possibilities of sexing day-old Denizli Fowl by means of slow and rapid feathering characteristics. First generation birds insert ignore into journalissuearticles values(253); were classified according to their day-old wing feathering types as follows: 40 chicks had primaries longer than the covert feathers insert ignore into journalissuearticles values(rapid feathering);, 81 chicks had primaries shorter than the covert feathers and 132 chicks had primaries equal to the coverts insert ignore into journalissuearticles values(slow feathering);. By means of test crossings amongst the rapid feathering males and slow feathering females, 63 male and 49 female day-olds were obtained. The male group consisted of 5 rapid feathering and 58 slow feathering day-olds while the female group consisted of 38 rapid feathering and 11 slow feathering day-olds. Feathering rate records were also kept for the birds at 9 weeks of age and shank melanization differences were recorded for the day-olds in different sex groups.
