Where to buy feed for Ducklings?

[Uprising]

I am planning on getting hatching duck eggs soon, so I still have plenty of time to figure this out (I hope) and I need to know where to buy duck starter/duckling food. Where do you guys buy them? I can't find any feed that's by me, and I may have found some online. What do you recommend? Where do you buy your feed?
Thanks!

Farm supply, but i have several within an hours drive from me. There are no feed stores near you at all? online i suppose is a possibility but i would think that would be costly due to weight of the feed, in my country that would be outrageous to buy that way... costing a fortune in postal fees.
