I'm planning on fencing my new chicken yard with 5' tall welded wire fence. The holes are 2" x 4". What are the pros and cons of this type of fencing? Will it be sufficient? I have heard horror stories about chicken wire so I didn't want to use that. Obviously the holes are big enough that a weasel may be able to slip through or a coon could climb up it, but hopefully my flock will always be inside the coop at night, so the coop will protect them better than the fence. Your thoughts on this?
