Same here b2simple, my stand is next to a soy field also and they are feeding on the corn like no tomorrow.Thank you for posting this question.
I heard they may think the brown soybean is bitter, but when i ate it , it was fine to me ??
Appx. 3 days ago a doe came out in mid-day to eat some and then i also spooked some deer while walking to my stand in the soy field, so i will stay where i am at for now.
