Start by bringing a pot of water to a boil. It's best to use a medium-sized pot with enough water to cover the eggs by about an inch. While you wait for the water to boil, take the eggs out of the fridge and place them on the counter.
After the water reaches a boiling point, lower the heat to a gentle simmer (with no bubbles). Carefully use a spoon (or skimmer) to slowly and gently add the eggs to the water. Once they are in, turn the heat back up to bring the water back to a boil.
Set a timer and cook the eggs for 6 to 7 minutes for soft-boiled eggs and 9 to 12 minutes for hard-boiled eggs. While the eggs are cooking, prepare an ice-water bath.
Once the eggs have cooked to your preferred time, use a spoon to remove the duck eggs and immediately submerge them in the ice-water bath to stop their cooking.
Carefully peel the eggs. Then slice, season with salt and pepper to taste, and enjoy!
