That's exciting you're getting your own chickens! You'll need somewhere to keep them and sounds like you're remodeling a shed. Check out our Coop forum if you need ideas, as there are hundreds of ideas built by our members there. Some have step-by-step instructions too. Our Learning Center might also be helpful, as it's full of articles about hatching, raising chicks, and chickens, and more!
