1. Preheat oven to 500 degrees.

2. Trim duck of all visible fat. Using a fork, prick the skin all over without piercing the meat; season with salt and pepper. Place duck on a rack set in a roasting pan and transfer to oven; roast for 40 minutes. Reduce heat to 400 degrees and continue roasting until juices run clear when thigh is pierced, about 30 minutes more. Remove from oven and let cool.

3. Reserve any duck fat from roasting pan. Store in an airtight container, refrigerated, up to 2 weeks. Remove skin from duck and discard. Remove meat from bones; discard bones. Shred meat and serve or store in an airtight container, refrigerated, up to 3 days.
