Screen or hardware cloth in floor of raised coop?

[MadChickensVT]

We're building our coop a couple feet off the ground. A friend of my wife's had a weasel burrow through the wood floor of her coop and kill all her birds. Has anybody else had that problem? Would screen be enough to prevent that, or would I need 1/2" hardware cloth?

Thanks

I think hardware cloth would be your safest bet.
