I have been free ranging my birds from the start. They have their housing that is fenced in for safety at night. I open the door and let them out in the morning and they run all day. The problem is all the poo in the yard and on my porch. What i would like to do is fence them in. I want the fenced area to be big enough to be considered to be free range. So the question is, how much space do they need to be considered free ranged birds. I am willing to spend the extra money on fencing, i just want the birds to be safe and the yard to be poo free.
