That's a cool idea. Although it would look pretty awful in the garden!
So I was thinking-- seeing the thread here about butting raised beds right up against chicken runs-- if I put a raised bed on the far side of our run (it will be the west-facing side), is there any reason why I couldn't grow cucumbers in it, using the wire wall of the run itself as a trellis for the vines? My thinking is that some of the cucumbers would develop on the inside, where the chickens could eat them, and some would develop on the outside, where I could harvest them for table, and the vines would shade the run a bit from the western summer sun.
Would the vines damage the run in any way? Or block too much airflow through the run? Thoughts?
