When I began my flock nine years ago with two adopted hens, I was very concerned about the stink. Little did I know then that I had complete control over how it smells. By the time I added three six-week old chicks to the flock, making five, I had learned about poop boards in the coop and that cleaning them each morning kept the coop clean and odor-free. And I was also learning that keeping the poop in the run scooped would eliminate the smell there, too.
The biggest dividend to keeping the poop cleaned up is zero fly problem in summer. Flies are attracted to the odor of poop, and when there is no odor, you get no flies. I dispose of the poop in a compost pile and in summer, I dust the fresh deposits with a little hydrated lime. That keeps the flies from laying eggs in it, further eliminating the fly problem.
I use no deodorizers, and no PDZ. I tried Stall Dry once in my sand run, but it was too dusty and didn't really do anything the sand wasn't already doing quite well.
So relax. You will be able to sit on your patio and enjoy your odor-free chicken run.
