A nearby feed store offers me, not wheat bran, but 50 pounds of wheat mill run for $12.14. https://en.wikipedia.org/wiki/Wheat_middlings
I didn't know anyone could transport 50 lbs. of anything in this overpriced city for $12, much less the all the most nutritious parts of wheat.
So is this stuff good staple for roaches?:
