This 1-quart metal waterer base creates a gravity-feed chick waterer when paired with a Little Giant 1-quart plastic screw-on jar or a standard Mason jar (sold separately). Made of heavy-gauge galvanized steel for long-lasting use, it features rounded, embossed edges to reduce chafing on chicks’ necks and heads. The base measures 5.5 inches in diameter by 1.25 inches high and comes in a case of 12.
