I understand not having room I had to wait until I could talk the husband and his buddies into coop 2 build. coop 1 is 8'x12', I told em it was 4 ft too narrow for my plans. Can't really build pen and separate space for storage or a small pen for injury. So coop 2, I worked many 12 hour days to make a good fund up for it and got a 10'x16' coop for it. Pen for 15, one for a pair, room for storage and room for a triple tier brooder. Plus a add on to my run.It takes time just hang in there. Just ry to make it as secure as you can is the main point. Oh and I have rare coops, log cabins from landscape timbers. Yeah we went full chicken crazy, but they had to match our cabin per my husband.
