Ok. So I might sound DUMB but I have NEVER had chickens before, so I figured I'd better ask before building and making a mistake. I have done my reading, and know that chickens need at least 3sq. feet per bird inside the coup. Does this just cover floor space or vertical space as well??? Example of this being Do I need (for 6 chickens) a coup that is 6X9 feet floor space and whatever high, or can I go for say 5X5 and maybe 5 feet high with ladder roosts?? Now this is in addition to the out side run. Which I am thinking of being like 10X20 or will that be too small?? Or will they be spoiled?? LOL .\ I am asking questions before I start building, but I gotta get started in the very near future!!! They can't stay locked in the bathroom forever!! LOL. I have VERY curious Kitties!!!
