For our current fox proof run we have 19 gauge chicken wire. I know in theory a fox could chew through it but so far, so good. The main problem was that it can't really be stretched tight so it looks baggy and not that attractive - although in a way this is a positive because it makes to practically impossible to climb especially with the overhang as well (one cat can make it up over an end post).
For the new one, we were going to go up a gauge to an 18 gauge which is much less chewable. But then I started looking at the ads in the smallholder magazines for
www.wiremeshfence.co.uk. It looks like it would be neater and strong. Clearly more expensive but this run is going to be so big, we want it to last for a good 10 years. We're going to get best quality timber so the wire needs to last too. With this one, we're going to just run several strands of wire (barbed?) across as an overhang, rather than trying to pull the netting out so it doesn't need to bend.
Any advice? Have any of you used the knotted wire? Benefits vs. chicken/rabbit wire? And vs. weld mesh?
