I discovered the plastic stuff last year and bought a roll. I love it - cheap, lightweight, easy to work with. However I am using it to fence in my vegie garden so the chooks and rabbits can't get in. I wouldn't trust it to keep my chickens safe (I also live in an urban area and have never seen a raccoon around here but wouldn't trust that one won't eventually discover the possibility of a chicken dinner, even in town. I've seen raccoons in some VERY urban areas over the years). The other thing about the plastic stuff is that sunlight degrades plastic really quickly. Since I am only using it part-year (taking it down when the vegies are done for the year), I hope to get several years use out of it, but nothing like the length of time I could use wire for. If you don't mind the idea of having to replace it every year, you could give it a try, but you might find that after 2-4 years, it would have been cheaper to just get the wire.
