The OP is not likely to reply as she hasn't been on the site for over 3 years.Hi how do I you clean ur coop? Like what do you use? It looks like sand on the main part? Just curious I've been having alot of experience with different things trying to find what is best for them
I suggest starting a thread in the Coop and Run Forum to ask your questions.
The use of sand works well in hot and/or arid climates. Everywhere else, I've not read favorable reviews.
IMO, the best thing to use to keep the coop clean are poop board and a large, attached, fully predator proof run.
