What's Happened to my House???

My chicken room is begging to be cleaned out.  The chickens are not happy.  Granted, this is the time of year when most chickens are taking time off from laying.  Egg laying is directly related to the amount of daylight the chickens get.  We are quickly approaching the shortest day of the year so one can't expect too much from the girls.  I wanted to muck out their room to encourage them to start laying again once we being the long climb back to the light.  I would also like to be able to go in the room to take care of them without sinking in the muck myself.  The room is about half done.  The valuable chicken manure is spread over my future flower beds to soak in over the winter.
