I prefer hardware cloth. The thicker gauge the better, obviously. Much less chance for smaller preditors (snakes) and rodents to get in. Ive never used welded wire, but it seems to have bigger openings than the hardware cloth. I dont have a run as my chickens are free range, but i do use hardware cloth on my brooder box and inside the coop. Nuttin gettin through that crap. Ive also seen people spray paint it black on their runs and it becomes almost invisible from a distance.
