Details: RentACoop Twin Cup Waterer and Feeder (2 Gallons - with Automatic Fill) Package includes (1) 2 Gallon Waterer which can be installed inside or outside of your coop on wood or wire. Dimensions are 5.5 x 5.5 x 17 Inches. Your 2 Gallon Waterer comes with 2 Auto-Fill cups for summer use (Hens can dip waddles in water to stay cool when drinking) and 2 horizontal freeze-proof nipples for winter use. Comes with all necessary hardware including 2 screws for installing on wood and 2 custom metal hooks for hanging on any type of wire (even 1/2" hardware cloth). Your waterer includes 1 extra horizontal nipple and 1 extra auto-fill cup along with setup and training videos for your chickens. Check out the video for more information. Note that this waterer is made of thick plastic which does not allow light to enter the waterer. This means that no algae will build up which is very important for the health of your flock. You are not able to see the water level from outside of the container but any container that allows you to see the water level will allow algae growth and we believe this is a worth sacrifice for the health of your flock.
