Any ideas for homemade duck food?

[Prisoc Family]

With all the GMO's growing so rapidly, I am wanting to make our duck food from scratch and use organic ingredients but not sure exactly how to go about doing it. I have purchased some organic duck food from a co-op but would like to start making my own without using Corn or Soy. I guess I really need to know what and how much to mix for layer feed and where (if) I can get a vitamin supplement.
Does anyone have any suggestions?? Thanks

I recommend you buy a copy of Storey's Guide to Raising Ducks by Dave Holderread.

There's all the info you need for mixing your own food by age/purpose in this book. Tons of good info. This is my duck "Bible."
