I have one of those long skinny chick feeders and found by accident that a piece of 1 x 3 placed in front of the feeder helps to keep them from scratching pine shavings into their food. At first I sat the feeder on the board to raise it up a bit but they scooted it off the board. When I noticed they had moved it, I went to put the feeder back on and saw that there was no bedding in the feeder. Left it there for 2 days now and it's working like a charm. Gotta love a happy accident!
