Think twice about spreading bird seed with corn that has been modified, buying chicken feed, deer feed or other livestock feed with GMO crops within them. Especially if it is unsterilized seeds, and un-cracked seeds as they can germinate and spread to other crops wild or domestic. Pollen from plants can spread miles at times infecting far away crops. Even wild birds and other animals that are foraging can spread the seed miles and miles away by mistake and ruin genetically stable crops and the seed that they produce. Buy better, do better, live better.
