Preheat oven to 375 degrees.
Melt butter or ghee in a small pot and add hot sauce. Remove from heat and set aside to cool (about 10 minutes).
In a large bowl, pour hot sauce mixture over ground chicken. Add celery, bread crumbs, and egg. Combine until well-mixed.
Roll mixture into roughly even balls, about 1 1/2 inches. Place balls on a pan lined with parchment paper or greased.
Bake for 25-30 minutes or until cooked through.
