This gravity-feed Hen Hydrator provides access to clean water on demand. The translucent bucket was designed to provide UV protection to prevent algae growth and allow for easy viewing of the water level. Lid fits tightly to prevent spills and protects contents while easy-to-remove fill plug allows for refilling without having to remove the entire lid. Each of the 4 nipples can accommodate up to 4 birds. Hanging height will vary by breed but should be high enough so that chickens must reach up slightly to drink.
