I have a small run for 3 chickens with an elevated coop. My yard had been landscaped with river rock before we purchased it. I dug out the rock and landscaping fabric and placed the coop on the soil and then filled the run with pea gravel. I use wood shavings inside the coop itself and this usually get scratched around and mixed below with the pea gravel. I have a weekly routine of raking the gravel/wood mix and spraying it down with water to start dissolving the poop and that seems to work so far. We live in CO so it’s extremely dry and the run dries pretty quickly. I’m new to chickens and I didn’t take into account how many feathers I would be dealing with when they molted. So now I have a gravel/wood/feather mix in my run. Short of literally hand picking all the feathers out I don’t know what to do. Will they decompose with the poop/wood?
