I am looking for my 15-hen chicken house for a wall-mounted galvanized chicken feeder. I want to have galvanized to avoid that rodents go into it via the wall and it should be large so I do not have to refill every other day. The only one I could find are a $90 Free Choice Wall Feeder. However, I like much more this style: . However, as you can see on the overview page where you can buy this one, it is only for 10 lbs capacity (dimensions: 12.5" h x 8" deep x 8" wide). I would rather like to store up to 30 pounds. Any suggestions?
