The fold down benches that I installed in the chicken coop are still high on my recommended list. I used 2x4s, heavy duty hinges, two lengths of chain with lockable links, screw eyes, and a hook and eye to keep it in the upright position. It folds up so the chickens can’t poop on the surface, but is easy to fold down. It makes a great work bench for filling water, and is fantastic when I need to sit when I’m not feeling well but still need to tend the chickens.
