Wire mesh fencing / chicken wire or similar (Harrogate HG1)

I'm trying to protect my allotment sweetcorn crop from foxes. Some online research suggests a one metre high wire mesh fence is all it takes to keep them out, but I know foxes cheerfully scaled a 6ft fence to get at Mum's chickens, so I'm a bit reluctant to spend significant money until I've seen it work. And anyway there's a limit to what a few corn cobs are worth even though they are delicious. Hoping someone has something spare I could use for the purpose (in the Harrogate area).
