In a large bowl, combine ground chicken, breadcrumbs, egg, chopped celery, onion, garlic, paprika, garlic powder, onion powder, and a pinch of salt and pepper. Mix until well combined but do not over mix.
Form the mixture into 1-inch meatballs and arrange them on a plate.
Pour the buffalo sauce into the crockpot.
Gently place the meatballs into the crockpot, turning them to coat in the sauce.
Cover and cook on high for 2 hours or on low for 4 hours, until the meatballs are cooked through and have an internal temperature of 165°F.
If desired, garnish with fresh parsley before serving.
Serve warm and enjoy!
