Roosting bar “tower”

[BigBlueHen53]

Attached to the run, over wire fencing, all the way around/all sides/top of the run, but the apron is only 14.5" out from the bottom of the run.

I would think that would do. Most predators are going to start digging right at the fence. Anything that foils them is a good thing.

I'm a little shy of 18" for the apron. We have about 14" out from the run. We do have some pieces left from ventilation, should we add this to make it 18" out?

More would be better but I wouldn't sweat it over 4" unless you start seeing signs of digging around the perimeter (which then I'd consider adding more like another foot out).

Or if you have plenty of leftover material, then using it to overlap isn't a bad idea, though that would be a lower priority for me and just do it as you have time and material.
