In Storey's he talks about planing mulberries and grape vines for duck. What else do people plant mainly for their ducks? two more specific questions: *anyone plant a bush (say huckleberry or something) *in* the pen/run? How does that work out? Would it be compatible w/deep litter? *I'd love to have grape vines coming up over the coop. (thinking of a style sorta like the Garden Coop for chickens where there's wire on top and a clear roof and the vines could go inbetween). BUT I'd be building the duck house/run in the more shady corner of the yard -- some sun, but not a lot. What fruit vine would both: please my ducks w/some sort of good eatin' and grow well in semi-shade? (looking beautiful would be a nice extra too -- I want an eye-pleasing set-up). In online photos I've seen folks do hops w/coops. But I don't imagine the ducks eat them, and I'm not into the whole home-brew thing.
