Great looking coop and great looking birds. If I was you I would install a fence-charger. Looks like your fence is only 4 ft tall. I would put 4 courses of hot wire around it. Only costs less than a dollar a year to operate one. I put a 5-mile charger around my pen, 4 courses of hot wire on a 6 ft fence set in concrete. Can't beat the peace of mind knowing coons cannot climb in.
