They poop constantly. Unless things get out of hand, I let Mother Nature clean with rain. Some people do rake up poop regularly though. I don’t know how you’d get it off pea gravel except with the hose.I hear chickens poop a lot. i Plan on keeping them in the part of the yard with pea pebbles and another part of the yard with dirt and grass. How do you clean the ground?
Great synopsis!People who use sand in their runs scoop it like a catbox frequently but it reputedly gets smelly in wet climates.
I'm a fan of deep litter in the run, which is a form of cold composting where you use a mix of compost "browns" as bedding: wood chips, shavings, pine straw, straw, etc. and keep layering it on until it either becomes inconveniently deep (spilling out the run door, etc), or you need some compost for the garden.
Some people with large runs and well-established systems never clean out the run. I had to clean it out about twice a year -- or any time that I developed an odor problem that couldn't be fixed with another 4-6" layer of pine straw/shavings.
I have no experience with chickens and gravel, but I can only think that the poop would run down into the gravel when it rains and create an odor problem that can only be solved by taking the gravel back out with a bobcat.
if you're not planning on laying down bedding, I bet you could just hose it down
