Welcome Cody A.!
We have fond memories of Ruston. Many years ago my sister lived there while her husband went to La. Tech. And, one of our boys finished there in architecture, the other in electrical engineering. Ruston reminds me of my home town - Natchitoches.
Regarding coop design, have you looked at the myriads of sizes and designs in the "Coops" area? (Button at the top of the page.) When I was anticipating building my coop a few months ago, I got some really good ideas there. I think many of them are designed for flocks smaller than what you anticipate having. Nevertheless, I'm sure you can expand on ideas you get there. I also got some good guiding principles of coop design from an eBook, The Small-Scale Poultry Flock" by Harvey Ussery. But, this source is one of many books out there that can be of help to you. I guess being both a teacher of science and computers (retired), I read, read, read on any topic of interest. I love the combination of using the Internet and books to bone up on things.
As with many others here, my flock is small, only 8 RIR. I wanted to start off small, but built my coop so that I can get more later, if I so decide. I don't know if it is practical for a flock the size you plan on having, but I am using leaves to create "deep litter" in the coop for controlling the smell and accumulation of manure, and it really works - no smell of chicken droppings in the coop at all. In late fall and winter, I make a few trips around Lake Charles residential areas and pick up a bunch of bags of leaves. The leaves not only go into my coop, they also add to my compost pile for my garden. Also, one end of my coop is covered with hardware cloth so as to allow for a lot of circulation of air. Both ideas are from Ussery's book. Of course, 8 birds don't produce much, and they are out into a tree and grassy area during the day.
Not related to your coop, but FYI, I've surrounded their pen with an electrified fence. Easy to put up and provides good security.
Hope to see more of your postings here. Disappointing to not see more of our Louisiana neighbors posting here. With the surge in the last few years of folks having chickens, you'd think there'd be more. Maybe they are just too busy tending to and watching their chickens.
