Well actually the feeder tray that they eat out of is too narrow for them to stand on. And the top of the feeder is like a 35 degree slant. So theres no way they can stand on any of it.
I just recently built this feeder for my chickens. I built this one because my bucket feeder was rusting out. It holds about 35 pounds of feed. I got the idea from Murray Mcmurray. Works like a charm. So I just thought I'd show everyone it. Here are some pictures.
