Does anyone mix their own chicken feed? in the past i have always used ground corn with some supplement (around 38%) and mixed it 5-1. i only had one local feed dealer that carried the chicken supplement, and now he has gone out of business (retired i should say). at any rate, one local old timer told me to mix soybean meal and ground corn would work just the same (again mixed at 5-1 ratio). my hens do free range around my goats and horses i'm just wondering if thats enough or if i need to find another dealer? i also give them vitamins in their water and free choice oyster shells.
