I use rubber livestock Bowls and the large ones for water and medium for feed. Yes sidewalk blocks or rubber mats under the water helps..Would you suggest to put the waterer on a block as well? Currently ours is simply a bowl on the ground and they keep knocking it over. They sort of dip their beaks in and scoop up, so we chose not to use one of the chicken waterers that we had which wouldn't allow for that scooping motion.
