In a bowl, combine sou sauce, hoison sauce, oyster sauce, ground ginger, minced garlic, and cayenne pepper. Place half the sauce in a zip-top baggy, reserve the rest of the sauce for after the wings are cooked. Add chicken drums to the baggy. Refrigerate and marinate for at least 30 minutes.
Preheat the grill, add chicken drums to the grill. Grill for 15 minutes, turning every 5 minutes. Make sure internal temperature reaches 165 degrees Fahrenheit.
Remove drums from the grill and toss with the remaining sauce from the bowl. Serve immediately.
