Right now my ducks(6 weeks) are still eating start and grow. We went to the feed store to get more feed and they don't have any purina duck grower or flock raiser, only cracked corn. They said that they couldn't order any either. From what I have read cracked corn is not good to feed ducks. Is there some place that I could buy feed online? This is really frustrating. Now I know why I should have researched more before getting ducks. But I want to do the best for them without paying a fortune in shipping costs. Any help is appreciated.
