Oh that is a rain chain.Would you please take a picture of the bowls (feeding bowls, black bowls, etc.) on a chain it is very intriguing?
I had always wanted one, but truth is they do splash so aren’t great if you get heavy rains and live in a house with wood siding.
I created an awning outside the Chicken Palace - mainly for my benefit as it is where I sit to enjoy hanging out with the chickens - and it doesn’t matter if it splashes a bit as it isn’t up against a wall. So I got a rain chain on Amazon. In the picture it is all dry, but mostly the bottom bowl fills with water off the roof and provides a handy source of wild water for the chickens. It also makes a nice noise. I like sitting out there in the rain. Very peaceful.
