I used to feed feeders but now they just eat smelt and night crawlers. I get my smelt from GFS food market. Its like 42 dollars for 11lbs. If you need a part number i can get it for you.
also there is another thread somewhere on here where someone was tying a knot around a peice of shrimp with the worm. idk try searching things like worm knot or worm tie.
