I bought the 78x118x118. Frame was easy to put together, hardest part is having to cut the chicken wire to fit around the frame and time consuming to place all the zip ties. You only get 1 tarp so half the run is covered for this size. I was missing one of the feet brackets and contacted them with which part I was missing and they sent me one free of charge within a week. My hens and Roo (13 total) are super happy with this and I am too. I’m 5’7” and can walk down the center so that’s helpful. I will be securing it with a more durable wire before winter to keep predators out and so I can wrap it in a plastic so my chickens can go out in winter.
