Hundred fifty day-old sexed Vanaraja chicks (75 male + 75 female) were selected and distributed equally in two groups. Birds were slaughtered by cervical dislocation method at 21, 42, 63 and 84 days of age and biometrical measurements were taken. From our present study we observed brain volume had shown significant (P<0.05) changes with respect to age and sex of birds. The mean length of both left and right cerebral hemispheres between male and female birds had varied significantly (P<0.05). With advancement of age, hemispheric length varied significantly (P<0.05). The major finding was that cerebral width significantly (P<0.05) increased from 42–63 days of age and in male birds cerebellar length increased from 63 days onwards. There were age-specific changes in all the morphometrical parameters where as between sexes there were some minor variations.
