Like the idea of keeping with the 'Main' house! The only problem I see is the cinder block foundation, I think it would shift and become unlovely or worse case scenario buckle over? Other than that a cool build.
Very well written, excellent source of information. The only thing I can think of to add is, Bob's, Blues, Gambles, Valleys and Mountain quail can be raised in large aviaries. They don't need to be seperated during breeding season if the enclosure is large and proper habitat is provided...but for the purpose of this article it is best for someone who has no knowledge of quail, to follow the author's advice.
Good job Leyla!
