The 2X4 board is so the chickens can cover their toes with their feathers in cold weather; a large enough branch will work as well but it's easier to nail a 2X4 than a 3" diameter branch
I second the poop board with PDZ, morning scooping takes 2 minutes tops. Too bad half my chicks are using the ladder to roost on instead of the actual roosts lol.
I liked the bucket nest boxes also but I used 50gal plastic barrels for dog houses at one time and no matter how much bedding I put in it some dogs always slid around in them like they were in a washing machine so I decided to go with wood instead. Not to mention I made a lot more nest boxes out of wood for cheaper than new buckets would've been.
