Otherwise, it is just an extension of the coop. It's 12'x28' with a solid roof and a 4'x8' extension off the back that houses the dust bathing area. When physically possible, they spend their day inside their pen. It is fenced in with poultry netting powered with a 10,000 volt/1.2 Joule output charger. The total area is about 1/3 acre.

But the coop also has a build-in brooder/maternity ward and 4'x8' outdoor area.

And I installed branches along the back of the run so the flock can preen and hang out there while they wait for me to let them out.
