Sorry to hear that you've lost the little one!
It sometimes happens that something is wrong right from the beginning. The other's knew that something was wrong and therefore shunned it. Mother Nature can be brutal but is always honest.
I doubt that the little guy had a disease or was contagious in any way, i assume a genetic defect, so i wouldn't be too worried about the other's. Adding extra nutrition and vitamins is always good for ducklings, just make sure they have also plenty of exercise, because fat ducklings will develop into ducks with leg and hip problems.
If you can, do buy the vitamin B supply that @Jpat has recommended and give them some extra, you can't overdose b-vitamins, the excess will just be peed out.
And if you have some pictures fur us duckling starved duck junkies, here are the two current duckling-threads:
