In a bowl, beat cream cheese and 2 tablespoons butter until smooth. Stir in chicken, milk, chives, pimientos, salt and pepper.
Separate crescent dough into four rectangles; firmly press perforations to seal. Spoon 1/2 cup chicken mixture into center of each rectangle. Bring four corners of dough together and twist; pinch edges to seal.
Brush tops of bundles with remaining butter. Sprinkle with bread crumbs. Place on an ungreased baking sheet. Bake at 350° for 20-25 minutes or until golden brown. Tie a chive around each. Yield: 4 servings.
