Our chickens have started to learn something. It is a secret the ducks have not be willing to share. The water in the bucket is WARM! To drink from it on a cold day is like having a hot cup of coffee. As the temps have been dropping and the winds have been picking up they are starting to learn. The white bar across the bucket is to keep the ducks from using the bucket as a hot tub. A few years back we had a larger tub and the ducks would take a swim in it at 5 below and wonder why their feathers froze when they got back out!
