I am just getting started with chickens myself. Meat birds in 7-12 weeks sounds good to me. Our order of chicks will be in mid-may. I honestly haven't done much research, my wife is all over that. I’m on board, and know soon I'll be building a coup from the bottom up, 4 x 8 x 6high. I have some 4x8 ¾ plywood and some rolled roofing so far. I want to insulate it for the winter and have it so I can open it up for the summer, and have a nice ventilation fan. When the chicks come, I'll start to think about it some more.
I got this book for my wife at boarders,

I got the book for the maintenance stuff, which my wife is taking the lead on. I'll build the coup and clean it out. The book also has ideas on coups. A good point in the book is the flooring. The book changed my thoughts on flooring, I was thinking plywood. Instead, I will be putting a thin concrete layer down instead of plywood. The book says you'll never be able to fully clean out the wood floor, that means it’s going to smell. I think the concrete will clean nice with a pressure washer and some light cleaner. Hell, maybe some type of cheap tile would work ontop of plywood.
I understand that a cold draft will kill chickens, or get them sick at least. You don’t want a vet bill on top of everything. You want it tight for the winter, you need to figure some type of door for the winter. Maybe a little bucket-o-day stove too.
Forget a 150 watt heat lamp 24/7.
As always, send pics. I'll send mine.
