I wonder how this plays out in the US. It's been nearly impossible lately to find organic black-oil sunflower seeds, but the chickens love to find them in their scratch mix.
Their favorite organic scratch mix with sunflower seeds seems to have been discontinued last year, so I recently bought a bag for wild birds.
Unfortunately, there wasn't an organic option, and the seeds are so shiny

So I called the number on the back of the bag to check if they process them with pesticides.
That phone number led to a phone-tree with a long wait that eventually resulted in a deflection to another company's customer-service line...then I gave up. Maybe I should revisit that quest to see if they'll give some kind of statement about how they process the seeds.
