I had to break the top layer of ice several times today.![]()
What I do for all my bird's water, except for the emus because they have a stock tank, is I put buckets in heated dog bowls that I can buy on Amazon for $15. It works great. I have two smaller ones that I think would be perfect for the pigeon waterers, either by tucking them in like I do with the buckets or flipping the bowl over and setting it on the bottom.
