AB  - This study was carried out to determine the effects of eggshell temperatures during the hatching period on incubation results and broiler performance. A total of 1800 eggs with an average of 55-65 g was obtained from 42 weeks of broiler breeder flock. The eggs were randomly divided into three groups for temperature applications and placed in an incubator with the same conditions as 37,2°C temperature and 54% relative humidity during the first 18 days of incubation. After transfer to the hatcher, three different temperature manipulations were applied between 19 and 21 days of incubation: 1- Control group: (36,8-37,0˚C), 2- Intermittent; high-temperature application for 3 hours daily (38,8 - 39,0°C), 3- Constant; continuously high-temperature application (38,8 - 39,0˚C). On hatching day, the chicks were weighed individually. To determine the effects of temperature manipulations during the hatching period on broiler performance, the chicks were reared under the same conditions. At the end of the experiment, body weight and body weight gain were found to be significant (P
