Welcome to BYC. If you look under articles there are a bunch of coop designs there. Good luck. Remember to build bigger than you think you'll need. Chicken math strikes and then before you know it your coop is too small!!
Welcome. It'll help folks to make recommendations if you update your profile to show what part of the country you live in - not to stalk you, but to know what kind of weather and climate you're building for.
Roughly how much money do you have to spend on the coop and the run?
Roughly how much space do you have?
A weekend's not much time to do a "from scratch" build.
