I can see where the wire stretcher would be handy, but can't recommend chicken wire as suitable for a run (or coop)...it just isn't strong enough to keep a determined predator away from chickens.
It may have taken a while to build, but you did a nice job on your coop. The run is amazing, very roomy and I like the roofing you put on it. Good tip on the tool for cutting hardware cloth!
Would have been nice to see pictures of the inside. I'm also wondering how predators are kept out as it looks like the ramps lead to just an opening. More detail on how it was made would have been helpful.
