Is that electric poultry netting running around the base? If not, what is it?
If electric poultry netting, that means you have a charger, so you could put something like alternating metal bars as your ladder? Make alternating bars hot and grounded? A chicken could hop from bar to bar and be good, even if perched on a hot one. A raccoon attempting to crawl up a ladder would likely touch a ground bar and hot bar at the same time. I might buy a ticket to that show.
If nothing else, make the lowest bar to the ground hot so any climbing animal touches it first. Birds could land on it or fly over it.
My roost bars are about 42" off the ground. I'm not sure if they could fly up that high, but I suspect they could. For now, they still hop up on an old hay bale as the intermediary and the last 2 feet or so from there.
