No - don't do outside-the-run coop. This is perfect! It's a chickeneer's dream setup. If you have foxes and the like in your countryside the more security the better. Even a dog can sleep through hearing or sensing a predator as our Rottweilers have proven to us and the breed is pretty aggressive and alert - but not if they're in a deep sleep. As dogs age they get less hyper/alert too. Dogs are great but not 100% foolproof security so the more security measures you have the better.
