I think you have answered this, but I couldn't find it in the thread. Sac's in Gonzales has organic layer feed and oyster shell. The brand is Nature's Wise. That's the only organic they have for chickens. Can you tell me anything about if I buy that and oyster shell if that would be good. Right now they are on Layena and they don't like it and also I want to go organic. THANKS!!!! I am in Baton Rouge.
