I also hang roll-up blinds from the eaves outside of my coop to cool one side where there are wire openings & windows. I roll it up or down to adjust for sunlight & storms, & it has spaces between the slats that allow some ventilation, like the one at http://hardwaredistributors.com/bli...os-wood.html?gclid=CIfN0OW7nL4CFYqFfgodM5cA0g.
I hang another one on the prop-out window on the end of the coop, and another curtain-y type shade over the other window. These ones provide shade, though don't add ventilation since they are right against glass.
I also lean a close-slatted section of wooden picket fence against the other end of the coop, which deflects sun from hitting that wall directly & provides a shadey, cooled area beside the coop.
