For <$20 one gets chapters on where to build, how to build, what materials, lots of info on general carpentry and 5 coop plans. It's written by 1) a do-it-yourself writer, 2)an owner of Horizon structures and 3)the co-author of the excellent companion book, 'Raising Chickens For Dummies".
Building a chicken coop is very personal. I've scanned the internet endlessly. There are tons of plans, a few graciously offered freely, but most you have to pay for the so-called schematics. I know what I want in a 'home': 3 chickens, easy clean, well protected-weather and pest, room for me to go inside the run, easy access to nest, cute appearance. Absolutely must contain slideout drip pans for fast cleanout! That's me.
The 5 plans are at different skill levels and needs:
1)the Minimal Coop- box shaped with single, sloping roof, simple hinged door, ~4'X4'X4', no adjoining run, good it states for 4-5 birds. Price tag ~$200 for building supplies. Easy;
2)the Alpine A-frame- 4'wide X 10'long X ~4'tall,, 2 nest boxes, screened run with door, 2-4 birds, looks cute, ~$300, not too hard, but you do have to cut some simple angles;
3)the Urban Tractor- 3'X6' with peaked roof 5', 2-3 birds, 16 sq.ft. run, tow chains to pull around the yard(put wheels on!), ~$400, looks neat and tidy; will take some work to build but totally doable for a novice like me;
4)the All-in-One(my choice & a similar version pictured on the front cover)- 8'X4'X7'tall, 4-6 birds(I prefer 3-4), one can enter the shelter and the run through short doors 3 1/2- 4' tall, 3 boxes, A real sloping roof(shingle it), ~$750 cost, add wheels and removable drip pan, nice doors, a small window, it'll take a few weekends to make unless you're Joe the Builder.
5) and finally, the Walk-In- 8X8X9'tall, 30 chickens?, 10 boxes, no run given, $1000, need some skills or help.
The designs are well done, easy to follow with step by step instructions. They list the materials needed, give lots of Tips and Warnings as expected by Dummies. They also include a few chapters on doing things differently: like water supply, electicity, storage spacefeeders, removable drip pans- highly recommended, retractable roof, automatic doors, etc. These are stated with general suggestions, not actual specific plans.
The book itself is larger in size than 'Raising Chicken for Dummies' which makes it easier to lay out. Very readable.
I'm not a carpenter. I have very few building skills; however, last summer, I dove in and constructed an A-frame treehouse on stilts from Stile's 'Treehouses and Other Cool Stuff'(see my review). It was a lot of fun and hard work, and a great learning experience. The plans here are much more comprehensive than Stiles' basic but adequate diagrams/instructions.
You will need some basic tools: circular saw, jig saw, drills, level, square, etc. They mention that a table saw and miter saw sure would be great, but you don't necessarily need them. Just take your time and have fun. Even if you don't use or like their specific plans, the rest of the book is immensely helpful. If building the coop is frustrating or too bothersome, just carefully choose and buy one, and enjoy your chickens!
