Split, they have the color of a popcorn seed

Soybeans

Chickens won't eat them. I can see why, they are too big to gulp down

I see whole kernel corn and yes those round little balls are soybeans. Go on Ebay and buy a small roller mill. Im a retired dairy farmer so l kinda have seed knowledge. I run all my scratch grains thru a roller mill.
