Have seen worse for sure. If I was you, I would immediately add a 24" or 36" tall run of chicken wire to the bottom of all fencing. Coons will pull an unwary bird thru welded wire like yours a piece at a time. You would not want to see that, ever. I met a guy who saw two coons do a tag-team thing where one stampeded the birds to the far side of a narrow 8'wide run to where the other coon waited to grab it thru the wire and tear it to pieces. They actually got 4 of his birds that way before he could get outside to the coop to chase them away. And this was in the daytime.
