You know the legal term "unmerchantable quality"?
It basically means that a product is simply not good enough to be sold... it cant do what it is supposed to do.
The roof leaks
The nest box leaks
The catches rusted at once
The rain gets in the window
It twists when you try to move it and you have to try and get it aligned again
It is designed in Australia and made in China
I think these coops are "unmerchantable quality" and if enough customers complained to their retailer, and gave them enough grief, they might stop importing, selling and make a fortune on cheap chinese products.

Approximate cost: $595
