As another reviewer has said tends to leave a small gap between house and pen, but pretty easy to fix and keeps the chickens dry and happy.
I have had several of these covers over the years and although they are good quality, heavy duty covers, my main issue is that they are a few inches/cm too short from front to back. This means that there is a gap, either at the very front of the run or at the back where the coop meets the run, which lets in rain. Very frustrating and not nice for my chickens, but very easy to fix if the covers were approximately 10cm bigger!
Brilliant cover works really well clear side keeps off rain keeps food and water dry and clean, combines with shade for sunny days. How comfy are "Merlin my Cockrel and his Maids"..
