Hi All - I'm a newbe here but have had chickens for 4 years. I currently have close to 70. They free range on 5 acres and I sell eggs. I have been buying Nutrena ~ Nature Wise. I Would like to go no soy/corn and maybe organic. However, the cost of that for the number of hens I have is, $$$$. I am wondering if anyone has any suggestions on where to maybe buy bulk or ideas on a good mix I can make myself? Thanks for any input.
