Thanks so much! I'm planning on building one of those PVC/hardware cloth and bird netting runs that are pretty cheap to make. I can't free range because of hawks and ospreys in my yard. There's a BIG ole nest in my back yard. I want them to have as much space as possible. And yes, I agree this will not fit any more than what I have! It says up to 8 on their website but them must be talking about Brahmas. lol. not full size chickens. one of mine is small but not that small.
as for the run, it's pretty cheaply made but I think it'll last longer with the waterproofing, and raising it off the ground, and gluing all of the pieces together as I joined them with screws. I like the overall design. I did add a latch so that I can open the glass part of the window without it flopping around if it gets windy!
as far as covering it, I think we are gonna get some heavy tarps because we get bad hurricaines and tropical storms here constantly in the fall. I am also going to stake it to the ground although, since I added a 4x4" base, I doubt it's light enough to raise off the ground as it could have before.
