Our tractor supply usually has Flock party and Purina layena. Both good products. If they have the layena mash I get that and the Flock Party scratch.
Part of the problem I have in getting what I want is because I only use pellets. Crumbles and smaller just get ground into the dirt and half of it wasted. The pellets will at least survive being buried until they are scratched back up again. I found this out by trial and error against tradition.
