The translucent bucket was designed to provide UV protection to prevent algae growth and allow for easy viewing of the water level. Convenient twist locking lid is sloped to prevent roosting and makes cleaning easy. Patented Bucket Handle Grip (Model #166713) for comfortable carrying with plenty of clearance between hand and bucket while still allowing the hen hydrator to be hung Each of the 4 side-mounted drinking nipples accommodates up to 4 birds and allow for easy access. Comes fully assembled. Hanging height will vary by breed but should be hung so the nipples are at the bird's eye level. This waterer is recommended for adult birds only and is not recommend for use in freezing weather. For best results remove all other water sources and tap each nipple so chickens can see water dripping. Acceptance of this watering method may take time but once a few birds begin to use it, others should follow. Available in 1 Gallon and 3 Gallon versions.
