Oh, you should have plenty of room with such a big coop. They have over double what they need per bird inside the coop and you figure they aren't all in the run or coop at the same time during the day. I love my australorps, they are sweethearts. Most of the fencing is 4 foot tall (I think) welded wire. I will post a pic on here of the pile of stuff I have gathered up. We dismantled several pens so the property looks tidier for when we list the house. I have a few more rolls to drag in and the lawn mower just ran out of gas and there isn't any more in the garage so I will have to make a trip to town. Sigh.Josie my coop is 11x14. What type of fencing & how much. I'm thinking of adding just a few rir or australorp
