I have a 8x12 wood shed with one large door and one window at the opposite end of the shed. How would I go about converting this to a chicken coop? I was thinking about maybe cutting off the side walls and leaving it open with both sides leading to a 12x15 walking area for the chickens. I am planning on purchasing 10 hens and 1 rooster but would like to design something big enough to allow room for expansion. I haven't really read too much into owning chickens yet but just wanting to get people's opinions that new about raising chickens to see if the shed would work. Thanks in advance.
