I did not finish the cages in the shed. I am debating right now over quail in the shed or the garage. I would like them in the shed if they will be alright through the winter. I can get pretty cold here in January though... so I am worried.I like your 4 ft box and the stackable idea jus donno how id incorporate it so am anxious to see what you come up with. I read your shed build last night did u ever finish those quail cages? Its not warm enough and still a garage consideration?
