Great space for your chickens! I always love it when people re-use materials.
At first I was conerned about the size and emptyness of the run. But its very nice if they free range during daytime.
I have one concern though. It seems a hell of a job to clean if you get bird mite in the coop.
Nice coop and nice run. The run looks almost bear-proof!
A little more details about the built itself, where the material came from - some wood looks reclaimed? - and what challenges you faced.
