OOOOHHHH!!!! Excitement!!!!! Info, please???? What is your general location? How big an area are you setting up for your garden? For your coop? For your run? How many birds to you hope to have? Are you new to chickens? New to gardening?
What is your soil like? Is your yard void of trees, or do you have to work around lots of shade and tree root issues.
General recommendation is for 4 s.f. in coop and 10 s.f. in run per bird.
There are lots of different ways you can set things up, and each way has it's own advantage/disadvantages.
Tell us how much room you have to work with, what you have for soil, how much available sun, how many chickens you want, and how much time you intend to spend gardening, and we'll be happy to help you out! Any physical limitations to gardening? Back issues? Do you intend to use a tiller?
Suggested reading: Any of the books written by Ruth Stout, Lasagna gardening by Patricia Lanza, view the Back to Eden movie. You can do a google search for it. Also, this book is very helpful for flock management:

I am absolutely passionate about gardening, and my flock is an integral part of that passion. I would LOVE to help you with your planning stages so that your garden/coop/run can work well with the space you have.
Immediate first suggestion is this: consider deep litter in both coop and run. This will provide LOTS of fantastic compost for your yard. Make your coop bigger than you think you will need. IMO, 4 x 8, with walls 6 - 8' high is an absolute minimum, no matter how few birds you intend to have. If you have a very small flock, the extra space will be enjoyed by your birds, and it will make your flock management a breeze instead of a headache.
I would place the coop on the back North side of your chosen area, with space for a run/garden on both the East and West ends of the coop. You could have a pop door on each end of the coop. The first year, you would use the East end for a chicken run, and the West end for the garden. When you finish harvesting your garden, you could then open the garden, and close off the current run. This would allow the soil to rest in the old run, while the birds glean the weeds, left over plants and insects from the old garden.
