what kinda drum do you have and type of feeder? we have 12 feeders going and only ever had one clog.that one I added some pellets that I had to the corn and it swelled from fog moisture.only had one bag of that and haven't gotten any more and haven't had any more cloggs.

I have 3 30 gal. garbage cans and the rest are drumbs with boat wenches to crank them up; all have funnels and Moultrie feeders on the drum.no problems so far. some have been running 24 -7 for 7 or 8 years.
