Mike, in my opinion you are wasting your money on non-gmo feed. I know there are zealots out there that are true believers but they just won't accept the science that proves that there is nothing in gmo foods that will hurt us or our animals. I am a beekeeper and know doctors that are beekeepers too and they have given me a new awakening that has disproved my old concerns. If you want to be concerned about your food I would suggest that you look closely to the neonicotinoids.
