I am wondering if it would work out to use welded wire fence ( 2in x 4 in ) to fence in the coop's run . I would make a 2ft apron extending outward from the run so predators can not dig under . Then I could run hardware cloth a few feet up the sides of the run . I would think that animals will not be able to chew through the welded wire fence . I just found a good deal at the hardware store for the fencing 4 ft X 50 ft for $10 a roll.
