And your zip code doesn't appear in our order list. I see you edited your post at 12:46 am and removed the claim that you had bought one of my feeders that was posted at 12:33 am. "Yeah I'd generalize things but I've built my own first and bought one of yours when that one didn't work. It is what it is but they don't always work." That came through the notification email.
Making one out of wood, yeah the dust and humidity will stop it quickly in many cases, IF you make the tolerances too tight. We sold wood feeders in the beginning, plywood, metal hinges. Some are still in use from 2011. The feeder grew into a all metal design except for the treadle step, the fit isn't tight on the moving parts, impossible for them to gum up due to dust or humidity. No one has to sift feed when using a properly designed treadle feeder and our feeders in the pictures are always immersed in poo,mud, feathers, and the only thing that stops them is the ammonia in the chicken poo that will rust out anything and it is usually the bottom of the feeder, not the moving parts. Even that doesn't happen if you keep the feeder up on patio blocks.
