Has anyone grown an espaliered fruit tree on the outside of their run? I'm considering putting in an espaliered fig tree outside my duck pen. I figure I'll let it get 2 feet tall before starting to send out horizontals, the ducks will keep it ant-free, and I can use the welded wire mesh for support. If you're not familiar with espalier, it's the practice of growing a tree on a two-dimensional plane like a wall. Every branch gets good sun, and for the space taken up, you really aren't going to get any more productive.
