In my coop, I have the layers food raised up on a few broken patio blocks, and the waterers are on cinder blocks, so they stay pretty clean...
If you have little chicks...I put the chick feeders and waterers on pieces of wood so they are slightly elevated, but are still accessible, and that helps, but no matter what, they are so active when they are that little, all that zipping around...you cant help but get some in the water, and just have to change it more often...you could try using a little less shavings too and see if that helps...
If you have larger birds, and chicks all living together, it may help to make a little area that only the chicks can get to so that the others dont keep knocking it over and making a mess of things..worked for me
