for the flower box, use treated 2x6 or 2x8 lumber. cut and assemble as shown.
install on top of run as shown, use scrap 2x4 to cross the joint and screw or nail together. I would angle the 2x4 down toward the far end of the coop to allow for better drainage that is not in the coop. the scrap 2x4 that holds this together will also hold the floor in. cut them about 45"
choose a place for your run door. cut and add (2) 2x4s and install as shown (dark brown in pic). this will hold your wire on later. take the width and height measurement, subtract 3x4 inch from each. assemble your run door as described in post #47 build out of 2x4, remember to subtract 7 inches from the height so the 2x4's fit flush instead of overlapping. I would use at least 3 hinges.
