This instructable is more on the meter but there are some guides on making the feeder around BYC. I like this guide so far.

Maybe they'll like the worms...
My ducks don't seem to want feed at all, they want only moving targets as food unless they're really hungry lol
I need to build one of those pvc feeders...
did you put it on the ground or hold it out for them? Mine didn't notice worms much until I fed them both a few, then it was ON
Our ducks really love that mock strawberry that's taken over our yard. They fight over it like they do with worms, each hunting out as many as possible.
