In large resealable food-storage plastic bag, mix 2 tablespoons of the yogurt and remaining Chicken Wing ingredients, adding chicken last. Tightly seal bag; turn several times to coat chicken. Refrigerate 2 to 3 hours, turning occasionally.
Meanwhile, in small bowl, mix remaining yogurt and Tzatziki Sauce ingredients until well blended. Cover; refrigerate until serving time.
Heat oven to 425°F. Line 15x10x1-inch pan with foil. Remove chicken from marinade; discard marinade. Arrange chicken in pan.
Bake 50 to 55 minutes, turning once, until chicken is no longer pink in center. Serve with sauce.
