add junk, clutter it up. Birds can then get out of sight of other birds, which will reduce tension and pecking. Ladders, mini walls, platforms that birds can get under or on top. Pallets and cement blocks can make endless arrangements, you can change it up.
Adding wind breaks in the run will let them out of doors, which is much more healthy. A rubber made storage tote, on the side will work just fine for a few chickens. Scraps of plywood can be set across the prevailing wind, some hay on the floor of the run. I use an old set of shower doors, and they have a sun porch. Does not have to be air tight, just blocking the wind.
Too many runs that I see here are just an open rectangle, with no shelter from the wind, no additional shade, and total non use of the third dimension vertical space.
It will look more cluttered, but it will actually add to the usable space the birds have access too.
