I am new to Backyard Chickens and have spent the past 2 days reading through everything and have seen arguments for & against only allowing free range & scratch feed. Commercial grain is not an option for my family because of the chemicals it has in it, even the organic feeds. We live a chemical, additive free diet and if we are feeding our chickens chemicals then we in turn are eating them. Does anyone know of any companies that make feed with no additives and/or chemicals and are organic? The only things I have seen is the scratch feed. Does anyone have a recipe they would be willing to share? I have pullets that will be layers and some that will be broilers.
