I need some feedback on whether this type of fence will keep my chickens safely free-ranging during the day. http://www.premier1supplies.com/detail.php?prod_id=44094 http://www.premier1supplies.com/img/product/pdf/44094.pdf We have a very sturdy coop and run, the girls sleep safely closed in, this would be just to be used during the day. We live in the country, so there are dogs running lose around us. thanks!!!
