Okay, so I need facts. I've always fed my duckies (two Calls) Agrimaster feed. Never really thought about it. A friend told me that the Purina Layena is better then Agrimaster's Layer food. So I bought a bag. $5 dollar difference, ouch. I compared the three top ingredients, exact same only different orders! Only thing is, Agri didn't have this roughage stuff in it. The top ingredients were: Layena: Agrimaster: Processed Grain byproducts Grain products Grain Products Plant protein products Plant Protein Products Processed Grain Byproducts Calcium Carbonate Animal Protein Products Roughage Products all the vitamin additions. THEN all the vitamin additions. So, based on this, what would you feed your ducks? I have a call pair as of now, hoping to add another hen. Thanks so much!
