I am going to convert my 2 hoop coops my SIL built into one large one similar to yours. I just need to figure out more about the huddle box & nesting box areas & how to combine the 2 coops. We've used them for the summer, since we live in North Dakota. I've been keeping the chickens in my husbands garage (taking up half of it) & he wants them out & I can't blame him. We have Chantecler chickens (a Canadian breed so they can handle the cold). DH made me a very large huddle box perch area that was insulated, so I have to probably cut it down in size a bit for it to fit. I love the snow photo, it helped me talk DH into using the hoop coops, so he can have his garage back. There is so much for us to figure out to make work for our area, but I am very inspired after seeing your permanent hoop coop.
You did a fantastic job & it is very inspiring.
