You will need to add something like 2 x 4 welded galv wire fencing to ht of 3 or 4 ft to be safe from coons. They will tear chicken wire to pieces. I know of one that tore up a steel catch and release trap. They are stronger than they look, and are always deadly to chickens. Real killers, that can climb and in pairs,will tag-team chickens in a narrow run where one stampedes birds to other side where other one will wait to reach thru and rip them apart. Your chicken wire will prevent that, but must be layered over with something like the welded wire, chain link, etc.
