The run is a not perfect rectangle, so I need to re-measure to get the exact dimensions, but the "long side" is 100 plus feet, so I think I'll be in a good place.
The yard is already fenced, and there's an existing run that contains the chickens well. It'll get expanded, and there's a few spots where I may swap out the existing fence with a bit taller one (the existing fence is a bit beaten up in one spot).
I expect the run won't have any vegetation, as most runs don't....but hope to use wood chips to keep it neat and tidy (yes, it'll be a LOT of wood chips...gotta work on sourcing!)
Again, still planning the exact logistics!
