Coop evolution

This looks like a great idea to save some money and deal with a hot weather location.

I am wondering how this coop has held up for you?

Now to my questions.... When did the 4x4 posts come into play? Are they to support the stronger roof? I see framing under the drop down tarps edge. How is that tied in? How ha it held up to hifh wind?

Nicely done, but I'd love more detail.
