What Miss Lydia said! Treats make all the difference. My ducks know I'm the source of all good things - letting them out to free-range, bringing peas, kale, mealworms, or other goodies. Not that they get treats all the time, but at least once a day they get something. I also spend time just crouching in their run for 5 minutes or so once or twice a day, just being still, watching and talking to them. Sometimes they will approach me and nibble on something. I always try to be quiet and calm around them. They thrive on routine and are easily scared, so I take that into consideration. Ducks don't love being picked up, but if you spend enough time and offer treats, they won't mind you being close, and will probably feel comfortable getting close to you!
