Made our feeder just like the blue one on here and today we were disappointed in how much the chickens were managing to waste. We did this one to keep wild birds from eating the food and the rain from dissolving the feed. With the cost of the black plastic bin and the PVC it wasn't cheap and still wasting food and attracting birds.

Here's a picture of the old gutter feeder that birds were eating from and the rain was dissolving the feed.
