Hi everyone, I have two 4-week old Pekin ducks and I think they're ready to move on to something with lower protein. Everything I find says to get them between 14 and 16% protein, but I can't find any waterfowl feed that low where I live. I considered chicken lay pellets but the guy at the feed store looked at me funny and tried to push 19% waterfowl feed. What would you folks suggest? They're on 18.5% protein starter crumbles now.
