I saw these wall feeders and am interested in them, but need opinions on them. The Fine X feeder has a screened bottom. What's the deal with that? The Econo is the same with a covered bottom. Which is better? Then I'd have to buy a cover? It looks they all cost the same no matter what size they are? Are these junk? The pics don't show the whole thing so it's hard to imagine what they're like. I'm also wondering what size I would need to feed 8 chickens. It would be nice to not have to fill it every day!
