I upgraded my review from 2 to 4 stars. The wire was construction cloth and the roof material seems sturdy. The boards aren't as sturdy as I expected for the price, there was no bottom wire piece under the run, there were no latches for the big back piece, and there is no door for the coop. Also the door into the run is hard to open when placed on the ground. I had to place it up on boards like a raised garden bed. This will need to be insulated and sturdied up before winter. Overall it seems pretty good but I had to add my own latches to keep out predators.
