In a large bowl, mix together the ground chicken, breadcrumbs, egg, onion powder, garlic powder, paprika, salt, and pepper until just combined. Do not over mix.
Form the mixture into 1½-inch meatballs using a cookie scoop or your hands.
Heat olive oil in a large skillet over medium heat. Add the meatballs in a single layer (cook in batches if needed).
Cook for 8–10 minutes, turning occasionally, until all sides are browned and the internal temperature reaches 165°F.
Reduce heat to low, pour the BBQ sauce over the meatballs, and gently toss to coat.
Simmer for 5–7 minutes, stirring occasionally, until the sauce is heated through and slightly thickened.
