We have 15 happy chickens that love to be picked up and petted. I have an opportunity to sell our excess eggs, but the health-food store insists that any commercial feed be organic. Our chickens are free-range, but I do supplement with oyster shells, layer mash, and scratch. I can only identify two sources for organic chicken feed in Texas--one 168 miles away and the other over 300 miles away. We really don't have facilities or space to grow our own feed. Any suggestions?
