In a large bowl, crumble the feta into large pieces. Add the grated kefalotyri, yogurt, and the eggs, lightly beaten. Add the dried thyme, finely chopped chives, and black pepper. Mix well. Butter a baking pan. Line it with three phyllo sheets, brushing each one with butter in between. Pour in the filling and spread it evenly using a spatula. Cover with the remaining three phyllo sheets, buttering each one separately. Fold the edges inward and score the pie into portions. Bake in a preheated oven at 180°C / 350°F for 60 minutes.
