We are planning to build our coop at the end of the garden, which is a brand new tilled area in a field overrun with strawberry vine. My thought is to build their run 3 or 4' wide around the entire garden perimeter (25' x 35'), or at least on three sides of it. I am hoping my 6 girls will keep the garden weed/bug free. Has anyone tried this? Does anyone see any problems with this idea? Is this too big an area for 6 chickens to keep up with? We do not use any pesticides. Thanks for any input you may have.
