It's been a week and I've had some success with breaking the pieces up, but not as much as I had hoped. The bass are more hesitant to take the irregular chunks than the bluegill are. Any chunk 1/2" or larger gets ignored by all. I did a little research on Purina's web site this morning and can't find any feed that is between 9/32" and 3/4". Does anyone know of any alternatives in a 3/8" size that I could use to train these bass on up?
