I built a coop which I found out later is not big enough for the 20 birds I now have. The coop is 14x6 (roughly) It is 8' tall. I'm wondering, if I were to add some sort of loft T one end. Say, the width squared. Would this be considered actual square footage. I figure I could easily add 36 sq. ft. This way and then it would be more than large enough. But, would I really be able to count the space? Thank you!
