Take a look at my byc page. My coop is on it. Notice that the ridge is all vent. You being in Texas, instead of going to the stained glass look, you may just want to consider having the belfry for ventilation.
I just went to find my byc page, and I have no idea where it went. Maybe they do not have them anymore. sorry.
You can also try doing a search for coops. I know there are a lot of adorable coops out there. And as long as you are a silky wedding planer, I think you need to read the thread on the lady that wanted to dye her silky pink for a wedding. It is GREAT!
