I used this coop as an indoor coop for 2 plymouth rock chickens currently 5 weeks of age. It is lightweight and made of cedar, and it assembled easily with extra screws provided. I took the precaution of drilling some of the holes through to the next piece of wood to be joined so as to not crack anything. If this coop were to be used outdoors I would have definitely attached additional hardware such as barrel bolts on the top and bottom of the run door and some sort of bracket on each side to attach the run to the coop. I would also block off the bottom edge of the run where it attaches to the house with wood so that predators could not get into the run from underneath the coop. All in all I am extremely satisfied with how well it went together and how easy it is to move. Everything lined up well and the construction is relatively solid for how light it is.
