I purchased this pen in 2013. I loved it. So easy to use and clean. You have to be careful when moving it and if you attach the roof with the screws provided you can't see inside or get to the chickens that are being difficult to catch. It was outside in rain, sun, sleet and hail and the roof held up as well as the rest of it. No leaks. Of course by 2015 it needed outside varnish, and stain, but that's normal for outdoor use. I loved this pen and so easy to use. I had to move so I had to sell it but I'm in a house with a yard now so I do plan on buying a replacement.
