Hi all! I do not have chickens yet, but am trying to pull together plans now so we can get moving come spring. I live rural and plan on having a large coop with a large fenced free range area for them because of my dogs. I was wondering how high I should have the fence to keep the chickens in? I plan on raising orpingtons and was hoping a 4 ft fence would keep their fat butts in. I am not worried about my dogs scaling the fence. They respect anything above 3'
