This is an extremely heavy duty hay feeder. I fabricated this out of German made wheel cages. Wheel cages are mounted on the wheels of a tractor for running in wet, muddy, unstable ground, made from heavy steel. I know there are no farm animals that can destroy this, lifetime https://offerup.com/redirect/?o=ZmVlZGVyLkl0’s heavy, can be rolled, best if moved with tractor. It would be great for small, miniature animals, cows, horses, sheep, goats, donkeys etc. it may have to be modified to keep goats from getting inside. It can be used sitting on the legs or turned upside down, if desired I will cut the legs off for you. I think it was a good idea and will work great, open to feedback/ criticism good or bad. 35” across 20” tall on legs 16” tall turned upside down 4-5” opening between tubing.
