Ordered this for family members in another state who adopted a chicken.  They did not assemble the pen yet as it is mid-winter at this time, but they did open the box and check out the contents.  They are very happy with the structure and strength, say the welds all look good and the roof-tarp is nicely thick.  The surrounding is green chicken-wire.  The only thing they criticize are the zip-ties, which are clear and not UV protected and will not last outdoors.  They will use their own zip-ties instead.  In all, they like it and think it is a good deal (and not just because I paid for it).
