I hate to be a big party pooper but with the way the roof is constructed on this coop, there will be plenty of moisture getting into the coop and onto the plywood floor.Deep litter needs some moisture in order to compost so is generally done on a dirt floor.
The pitch of the roof ends at the dog ears of the privacy fence that makes up one of the long walls.
The tar paper is pinned down behind the trim board, essentially diverting water onto the plywood siding and into the coop that way too.
The roof line needs to completely redone to actually shed water away from the structure and not have it run back in.
@Love My Chickies , where are you located in general? Do you ever get snow? Using the fence as a wall is a clever idea but it shouldn't be on the load bearing side. Is this structure just temporary until you can build something different?
