I was just curious about this one. I was checking out other weathering chambers people use. I originally thought of something that was just netted off with special avairy netting, then something more protective (some sort of wiring or chain linked fense system around that whole area.
However, I wondered if something like this would work: A basic wooden frame (8x12 in my case). Then instead of solid walls, just use metal bars, 1.5 inches apart. Same for roof. Would that be acceptable, or is the not exposed enough? Just a thought. Thanks!
