Years ago - actually about 20! - I had the best waterer - a round metal pan about 18" in diameter with a 'lid' of spokes that came together at the top - like a tepee, which clipped on and came off for cleaning and filling. Has anyone seen one like this? My plastic waterer needs two hands and my feet to screw the top back on after filling and I hate it. Any other ingenious watering systems (for 6 chickens)? Thanks. Am loving having some "girls" around again.
