Signature. BYC places it automatically at the bottom of all my posts.
Its my way of showing the limits of my experience. "This is what I have currently, this is how long I've had it", like my location at the left, it helps posters get an idea of where my opinion is coming from.
See my flock in Sig. The birds are essentially of three ages - either last year's late spring purchases, or the December+ hatchings, with the SLW splitting the difference. All are now integrated, sharing the run and house overnight, free ranging during the day. Actually, I need to separate...
The relative narrowness of the run provides some challenge, but otherwise, it sounds like you are off to a very good start. As @aart and other have said, places (not dead ends) to hide and break line of sight, and I think you are ready.
