I'm building a woods open air coop mini, which will have about 32ft sq for about 6 egg birds, and be moved daily unlike some of the larger ones that are moved less frequently. What are your thoughts on if I need a run during the 3 warmer seasons? (Current plan is to have it stationary in winter and attach a run probably because I don't want them to be forced to walk on a new patch of snow/ice daily)
