Most poo is at night while perched so every morning I take 15 min with my 5 gal bucket & kitty litter scooper & scoop out poo. If I see a chunky poo in the run I will scoop that too.
This 15 min each morning keeps the coop & run surprisingly clean overall.
Depending upon weather...many rainy days means more poo inside, I can clean coop & put fresh wood chips in when needed, could be 6 mos, could be 2 mos, just depends. My goal is to keep the humidity factor down, less humidity & less wet poo woodchips for overall comfort, health & absolutely no stink. The old poo chips go to a compost area where I till, so the soil is awesome for future gardening.
