Could you take a picture of that feeder? ThanksI exchanged a 4H green feeder with the little multi-seperators for a red Little Giant that had a lip on the inside of the bottom pan and one of those little multi-separators also so they couldn't flick the food all over the ground....worked like a champ...also I only give them a bit more than they will clean up in a day, and dump the powder that collects in the bottom tray at the end of the week. Mine weren't flicking it side to side as much as scooping it towards themselves and over the edge and out on the ground, the little bit of a lip stopped the problem, no more food on the ground.
