Looking for grower feed for ducklings, need recommendations

[anonymous99]

My ducklings will be 3 weeks old next week and I know that they’re gonna need grower feed to eat, but the problem is that I can’t seem to find any. I’ve looked online and tractor supply never seems to have what I need. I need grower feed that has the necessary protein and niacin requirement bc I know that they need protein that’s below 20%. Any recommendations would help, preferably crumbles with the proper protein and niacin requirements. It has to be non medicated too.

I'd recommend mazuri waterfowl starter, you can have it shipped to you from chewy.com
