Giving oyster shell free choice is the best way I've heard when you have drakes as well as females. When mine (all girls) were ducklings, I sprinkled tiny bits of grit on their food, then when they were a week old I started giving them peas and lettuce.
Phosphorus also plays a part in the calcium absorption for ducks, by the way. So as close to a balanced diet as possible is a good idea all around.
Enjoy those ducks!
