We haven't been lucky enough to find a storage building at auction or anywhere else cheap. I'm still looking for something that we could easily adapt into a coop.
Since we live in a neighborhood, our coop and run needs to look "pretty" so we don't have any problems with neighbors. I'm doubting our ability to make a "pretty" coop and run from scratch considering our limited carpentry skills, lol.
Ah, well... such is life. It was a good idea while it lasted.
