I buy what is in stock at Dillard Feed in Weatherford but I am sure the feed stores in San Antonio will have these.
Purina is more expensive so I use feed from Golden Oak Milling:http://www.goldenoakmilling.com/http://poultry.purinamills.com/OURPRODU ... fault.aspx
Golden Oak is cheaper and they have the 28% and 24% options that contain the fish meal and molasses but I used the 20% Laying Ration. Use the crumbles form which passes through any spreader very easily.
Check these dealers for Golden Milling:
