Truss spaces?

[joneus]

How do you predator/wild bird proof the space between the ceiling and the top wall plate where the truss runs over it? On my coop, its the width of a 2x3. I know a coyote or fox wont be going through that, but the chickadees, sparrows and titmice (not to mention mice and any weasels out there) could probably squeeze through there without any trouble.

I'm just curious to know how others have solved that problem.

Thoughts?

I stapled up window screen and hardware cloth to keep out wasp and small critters.
