I just finished wiring my new coop. I'll rent a trencher to get electicitiy from the house. The wiring will go under what will become a 12' x 16' run. Would it make sense to mark out the run on the ground with spray paint and then trench around the perimeter to simplify the burying of the hardware cloth? If so, would you trench before or after installing the 4 x 4 fence posts?
