The coop was poorly made.  All the pieces on the bottom of the tray came loose the first time I tried to take it out to clean it.  We had to make several repairs:  had to glue pieces back together that were broke when we opened the box.  Also the tray will not slide easily in and out.  I haven’t figured out what the problem is yet.  When I pull on the tray the whole coop moves because it is stuck.  I would not buy this product again.
