I’m doing a 6’x30’ run with 1/2” hardware cloth 3’ from the ground up and chicken wire the remaining 4’ I hope that’s enough to keep the ladies safe. The top is to be covered also.
I can’t tell you to buy it but I’m in the process of building my coop and run for my chicks. I’m in about $300. and your coop is much bigger and nicer looking then mine.
