For what I observed, first of all it is a very clean mix, no broken seeds, no broken corn, or dust, the "brown" seeds, if that is what you mean, are sunflower seeds. All I can tell you is that it is a very balanced mix, and the wild birds coming in "clean every single seed" and the tray comes out very, very clean. No dust of any kind. And the price is very, very reasonable.
yes.. all kinds of doves and other birds will eat this.
