ive read people use sand in thier coops and runs, and some people use shavings. i am still in the process of finishing my coop and run addition, but when i am done i figured i would put deep pine shavings on the floor in the coop, as well as a nest box or two, and some perches. the run that is attached is fully enclosed with chicken wire, but doesnt have a roof to block the weather. bad rain makes the ground in the run area wet, which will smell a bit. i dont think putting shavings down out there is a good idea because they will also get wet and smell. i guess my question is, do people usually have a roof on the outside run area to keep dry from rain? if not is sand a good idea or will that get equally as wet and a little stinky? just trying to set it up so its clean and will dry out quick to prevent smell.
