thanks. My coop is similar only I covered it with 1/2" hdw cloth. And I put a loft in the back half which is insulated. This extra construction detail is what made the coop too heavy to move. It was also a beast to cut each end panel to match the curve of the cattle panel. Of course the hoop is not completely symmetrical, so I had to make a template of the arc on either side of the loft door to fit the plywood... eight panels in all b/c I insulated it. I definitely would not recommend a hoop coop if you intend to put in a loft. The construction details were Way too difficult and time consuming. I thought I'd be saving time and materials by going with a hoop.... not so with the loft. I also thought I was being smart by putting corrugated plastic roofing over the loft. Not a good idea b/c of the discontinuity between the roofing and shade tarp in the front. Live and learn! It would have been possible to still insulate the roof by sandwiching the flexible Styrofoam between 2 layers of tarp, and foregoing the roofing material. If I ever build again, it'll be stick built using traditional framing. The advantage is that I feel that it's predator proof, and the girls can come and go from the upper level to the lower level. Lately, I've not been shutting them in the loft at night, allowing them to come out the pop door into the lower level in the morning.
