First I will start out asking if my chickens have access to the run on there demand do I need a roof on the run? If i didn't i would think a coon would get in and use the same door my chickens do and eventually just walk into the coop. With that in mind what is a cheap way to make a run for my chickens as far as the fence goes? Keep in mind i made my coop with scraps around the farm with a total material cost of 0 dollars The cheaper I can go the better. This isn't a permanent coop and will have to last from march 2010 to november 2010. Ideas?
