I live in Long Island and we have VERY limited choices at the few feed stores that are available. I am getting a pair of adult snowy call ducks next week and want to get their feed now. The seller suggests Nutrena feeds (which I cannot find here) or Kent Feeds...another unavailable brand here on the Island. I did order some kelp supplement, but that sure isn't going to help with their main ration. I was curious if those of you with call experience might give me the benefit of your experience with feed?
