The sellers of the property left their coop and a run. There were two chickens in it and they seemed healthy (although I know next to nothing about chickens), they took the chickens out today and of course they didn't clean the coop out. Im thinking our timeline for getting chickens will be in about 9 months, I know I need to clean the coop out but what about the run area? Do I need to spray the ground with anything or do anything to it? Or is it not safe the use the current run area at all? Thanks!
