I thought I'd share this in case it helps anyone else. We've had some big rainstorms out here on the west coast, and my traditional, open-top-hanging-gravity feeder is no good in that kind of weather. I tried finding a cover for my feeder, but they are not 100% waterproof because of the hole in the top so it can hang. I've been scouring the interwebs trying to find a CHEAP solution that doesn't involve PVC pipe and tools I don't have. Finally, I found this: http://www.avianaquamiser.com/posts/How_to_make_a_weather-proof_chicken_feeder/ Genius, don't you think?? Most people could find this stuff around their house or get it for free from a friend. I have a cat and I buy cat litter anyway. The only tools needed are a utility knife and a drill. I'm thinking about attaching a plastic lip of some kind over the opening to make it even more waterproof. Going to make two of these today!
