I have a small flock of 16 hens, my old house was in bad shape. I purchased this at my wife's urging. They say no tools required, don't believe it I needed a rubber mallet and once it snapped together there is no taking it apart. I placed it up on 8-inch blocks to help predator proof  it. All I can say is that my hens are happy, I'm happy, but most of all my wife is happy.
