So i am starting my first flock in the next week or so, just finishing up the coop/run project. I have been reading my copy of Storey's Guide to raising Chickens, and in there she mentions that a 2'-3' grid of twine or wire would suffice to deter any flying predators. I was wondering if anyone has had any experience with this and at the same time, if it does deter the outside predators, will do the same to keep the chickens in? Any thoughts on the subject are appreciated!!
