My father in law gave me this 8 x 10 building. It was covered in particle board and it was filled several inches deep of rat poop. When I tore the ceiling board off there was another several inches of rat poop and it was infested with silverfish. It was DISGUSTING. I wish I would have taken a picture of it then. I stripped it down to just the frame with help from DH and sons. We then put up plywood inside and out. We insulated and put 1/8 wire inside the walls and ceiling plywood to deter snakes, large insects and rodents. We put in 4 roosts with a table between the top two and bottom two with trays under all to collect poo. We put in two rows of nesting boxes and a brooder box. We still have to finish the outside of the building with metal siding so I didn't include those pictures yet. We also plan to add a run off the back. We free range the bigger birds but will keep the younger ones in the run until they get older.
