Chicken wire is one kind of woven wire, but it's not the only kind. All fencing meant to keep large animals in or out is woven wire. See the links Bear Foot Farm posted.
Farm fencing is useless for chickens (holes too big) but horse fencing (either diamond or rectangular) is super strong and works great, with the addition of hardware cloth for reach through areas.
I myself use chainlink kennels w/ hardware cloth wired on strategically. If you use VERY heavy gauge hardware cloth you can use it for the primary fencing material, but even so I would be careful. I have a 25 pound dog who DECIMATED very large gauge welded wire 2x4 fencing when it was used as a digging apron (inside the dogs' yard as loves to dig and sometimes digs around the edges). I'm talking TORE IT UP! He can't do that w/ the woven wire w/ which I replaced it.
