We started by taking off carpet from 5 2x4 and plywood (slabs) we got for $4.00 each We placed them with 6' presure treated wood legs on the 4 corners for about 7.00 each my son helping haul back the side with one of the legs ready to go Drilling 2 holes on the upper part, on each side, covered by wire for ventillation. The door doubles as their walkway up into their home. we attached slats to the doorway short enough to get the door closed The 3 nesting boxes we got from a friend (free) fit great inside and we made an opening to access the boxes. we need a roof next. that comes soon (before the rain I hope) We just have a sheet of Particle board on top for now. the waterer and feeder are atached with bike hooks below the nesting boxes. total cost $48. for the wood $16 for the hinges and locks. Lots and lots of Elbow greese. We plan on putting it atached to the outside area of the run about 1 foot lower in the ground.
