Age at sexual maturity, FCR and different conformation traits like shank length, keel length and breast angle at 5^th week of age was measured. Moreover egg production upto 40^th and 52^nd week of age and egg weight at 32^nd, 40^th, 52^nd weeks of age was recorded. Feed Conversion Ratio was recorded as 2.60 at 5^th week of age. Shank length (mm) 61.30±2.90, Keel length (mm) 53.90±2.80, Breast angle (°) 63.80±2.50 was observed in the study at 5^th week of age. At the end of 40^th and 52^nd week the egg production was recorded as 66.60±2.50 and 123.10±4.30 numbers respectively.
