Here's a link to how I built my hoop coop:Welcome to BYC!
There's a ton of information here, but you probably already realized that.
I came here looking for coop information, too. I was going to buy one, or build one from pallets, but finally chose a hoop coop design as I'm in my 60s, arthritic, and not very handy. I did one almost all by myself in just over a month of weekends and occasionally after I got home from work.
