I’m new and looking to get ducks. Been doing some reading and for the most part I’ve saw Purina Flock Raiser and nutrena all flock has been brought up a lot. I know the importance of niacin and grit and when laying eggs.. calcium. My question was, I saw some articles on growing fodder and feeding with the fodder. From what I’ve seen, they are feeding with just the fodder (wheat/barley) and just substituting with grit and calcium. Is this legit? I was looking at raising mealworms as well.
