Preheat oven to 400° F.
Line two large baking sheets with parchment paper and set aside.
In a large mixing bowl, combine the ground turkey, eggs, bread crumbs, grated onion, olive oil, garlic powder, sage, thyme, salt, and black pepper.
Roll the mixture into about 60 meatballs, roughly 1 1/2 tablespoons of the turkey mixture each.
Place the meatballs at least a half-inch apart onto your prepared baking sheets.
Bake for 15-20 minutes or until firm, but just undercooked.
Place the meatballs into the crock of a large slow cooker.
In a large bowl, whisk together both cranberry sauces, orange zest, orange juice, brown sugar, and Worcestershire sauce until fully combined.
Pour the cranberry sauce mixture over the meatballs and toss to coat.
Turn your slow cooker on high and cook for 2 hours or on low for 4 hours.
Serve hot with toothpicks or cocktail picks.
