You already had good advice regarding the nest box lip. The thing with a door is that, predator defense aside, if you're in an area that gets cold weather, it helps keep the cold out over night. Also, I've read about people using dowel rods too, mostly w/bantams. But unlike most wild birds, chickens don't really grab hold of branches to perch; their feet rest on an object (although their toes may naturally curl a bit), which is why a flattish object is typically better. Plus, if you're in a cold weather area, a slightly wider perch allows their feathers to totally cover their feet/toes when they sit.
