I just purchased: Brown's Encore Natural Chick Starter Baby Chicken Feed, 7-lb bag https://app.chewy.com/bbPsklFgrM I thought it was non-medicated. After reading the packaging thoroughly, it has Amprolium added. I am hatching ducklings this weekend and need a starter crumble without medication added. I am having difficulty finding it anywhere! My local feed stores - Nope I wanted to buy a smaller bag to start. Anyone have supplier or resource to suggest? Please help I wanna start these babies off right if I’m lucky enough to hatch call ducks for the first time.
