These larger Crown poultry waterers are a bulb shape and have a twist-lock for tight attachment.
They have wire handles on top which makes it easy to carry and shift them.
They have a flat top so you can stand the waterer upside down on the ground while you refill it, saving strain on your back.
Ball drinkers have the bulbed shape which helps to prevent chicks standing in the trough and soiling the water.
Available in 2.5l, 4l, 6.5l, 9l and 12l versions.
