I'm looking for a bag food to replace the organic, no soy, non-gmo chick starter that I have been feeding my ducks (yes, I've been adding Niacin). The bag should be finished in the next week. They are currently 4 weeks old. I keep reading conflicting info about how much protein they need at this age. Is 17% about right - I should be looking for a grower? What brands should I be looking for? It seems to be hard to find something organic in a crumble. I think I want a crumble...is that better, like less mess, or should I go for pellets (I'm just afraid that would be too much of a transition from their starter feed to pellets, but maybe I'm wrong)? I've googled and googled, but can't seem to find exactly what I'm looking for, so I thought I'd turn to y'all for help. And I did read other threads, but most brands suggested don't seem to be organic.
