I think I read somewhere that putting the feeder and water in a container with sand will help keep the mess down. We have chick feeder and waterer that use mason jars. But the bigger chickens keep knocking the water over into the wood chips, they seem to prefer it over their water, I'm assuming because it is new. If I put it in a foil pan filled with sand it seems that it should help with spills. I've heard it helps keep the chicks from scratching wood chips into it as well. Has anyone tried this or have other ideas?
