Over the years I've bought five of the 25lb feeders and two of the 10lb feeders. Most are attached to stands I made from 2x4s and are fully exposed to the elements — sun, rain, and snow. Sometimes I get a little bit of rainwater coming in through the mounting holes, but it's never enough to spoil the feed and never from the front. Most importantly, my chickens don't spill any feed on the ground!Recently I needed to add a few more 10lb feeders and thought I'd try to save a few bucks with a similarly designed feeder available from many anonymous Chinese sellers on Amazon. In those the feed sits higher and two separate flocks of chickens made quick work of putting all the feed on the ground. I'll be sending those back and ordering a few more of these.
