re: Feeding Rice bran ?

If you can find a 50 gallon drum cut small holes in the bottom where it can fall out, you need one with the lid you can you take it on and off.

Strap it to a tree on top of some bricks

This is what we do, you can put 3-400 lbs in it and it will last several months.

I usually just pour two bags out in a pile by my bow stand though
