Jill--are you talking about the big, brownish, round "seeds" that no birds eat?
Hmmmm--I have not noticed anything mixed into the Millet Big Lots sells. Maybe a few black oilers...
I don't know if it is white Millet--or the more common off white one. Light beige?)
There are a couple different shades
I always check the ingredients--and will not buy the bags that have those big, dark, round seeds..
ACE Hardware always sells these 20-LB bags of Bird seed. You can see--just by loking close--that
half of them are the round seeds. What are they called???? They are just fillers....
