You might try a compositing method.

Take four photos by moving the tripod just enough to move the wire relative to subject behind it, both sides and tops.

Then align them in photoshop as layers. That is make the grain silo overlaying each other. Because you're so far away, you shouldn't have any parallax problems. Then, erase (mask) the chain link in each layer. After that, turn them all on. You might have a perfect composited image then? Haven't tried this so don't know if it will work.
