I've been looking at waterers in the learning center but would like to know what everyone actually uses. Unsurprisingly, a water container sitting one the ground doesn't really work - they just mess the water or tip it over. Anyone got any suggestions for a cheap waterer you can make at home? I only have four chickens so I don't need a really big one but I do need something more efficient and hygienic (in other words, chicken-smart) than a regular ground container. Please post your thoughts.
