I bought this over the summer to use for my new pullets (4 total), and it has been serving us well this winter, in the high desert of Arizona, where the winter temps can get down to 0-10 at night.    You have to assemble it yourself, and I've never endeavored to do something like this before, but it was pretty easy, taking me a hours total.  It's pretty sturdy, although one of the hinges for the roof fell apart only a few weeks after I started using it, so I'm relying on the other one to hold up and not to fall apart.  I think it's more spacious than a lot of other ready-to-assemble coops on the market, and at a reasonable price.  I attached the outdoor chicken run from this manufacturer with mesh cover to it, which was enough space for them as they were growing; now that they're full-sized, I've expanded their run area with a homemade fence and cover.
