Hello, I'm trying to figure out how to predator proof a large wooden barn door. The outside is metal but the door slides along the wooden framing inside. The rest of the barn is very solid, no entry points at all (set on a 12" deep foundation) and it would be much cheaper to just seal the sliding doors instead of hardware clothing all 4 stalls individually. I'm wondering if the best way might be to remove the tracks split the door and rehang them with piano hinges. That would still leave the bottom edge which needs some kind of seal. I'm trying to do this cheaply because I got a bit carried away ordering chicks for spring and I'm feeling broke!
