8 Gallon Capacity Plastic Dome Chicken Water

I have found that by cracking open the lid each day will fill the water bowl to the max, then I close the lid. Easy peasy.

This waterer would probably be great for a flock of just chickens, however, adding ducks and geese they make such a mess in any waterer. This one is especially difficult to clean because the top screw cap is not large enough to put your hand in to access the inside of the jug. There is a spout at the bottom that gets really dirty on the inside, and is very hard to clean. At my house the saying goes "work smarter, not harder", so we replaced this with a different type.
