What brand of feed does Purina make that does NOT contain GMOS' Genetically modified organism ingredients? If only one brand is available, then why not make ALL of your feed safe? Pease don't answer with just a thinly veiled advertisement. I don't believe anyone is looking intentionally to add unsafe and untested GMO's to their chickens feed. It's bad enough that it's in most of the food now found on grocery store shelves (just look somewhere near the ingredients, as a recent law now mandates that companies must state it on their products), even though many of them have been adding it unbeknownst to the public, for decades! Aside from the company making larger profits using GMO's, what does Purina claim is it's benefits?
