Best options for duck pen roof.

I'm in the process of building my duck pen. I was at tractor supply yesterday and they had what looked like chicken wire but made out of a like a coated string. Would this work for keeping birds of pray out. Or should I use chicken wire?

If the ducks will be in that area at night it also needs to keep raccoons out
