Has anyone had experience with this sort of containment? I don't want a pen or coop for our biddies; instead, I prefer something which imitates freedom as much as possible. But, 100% complete freedom means devastation for seeds and ideals of squeaky-clean porches. So, I want a happy medium. And a sort of fencing around the perimeter of the chickens' allowed area is appealing due to its movable nature. I suppose I would have to clip wings too to prevent happy escape artists... Any feedback would be much appreciated!
