A small hook, like a cup hook, to hang a 6" paint scraper or putty knife inside your coop right by the people door. Invaluable when the inevitable "poop hits the wall!" I use it to scrape the roost (which my goofy chickens have decided is only good for daytime naps and not for sleeping on at night) and after tonight it looks like I'm going to have to scrape the 2x4 framing side pieces. They won't sleep on the roost, which is the same doggone 2x4 as the wall framing, but they will sleep ON the framing cross pieces tucked up against the wall. Well, I hope that only lasts until their butts get too big to fit!
