I did this last year for the goats and will do this again.I took an old tire stuffed straw inside the tire rim to insulate it. Then placed another on top and stuffed it in side the rim.I place straw in the bottom and placed a 5 gallon bucket in side the 2 tires.Filled with their drinking water.This was located inside the barn.It only froze over when it was really cold out .I the broke the ice on top that crusted over and topped off with new hot water. Which helped to melt the frozen top .
Now, if you could do this with one tire for the chickens bowl or pan. It would help to some extent.Outside, the sun would help heat the tire but it would still freeze on top.In front of a sunny window inside the coop would be great.
