As far as traps you'll want Victor #2 or so in size.

But you have to have a trapping lisence for your state and they must be in season and all other regulations must be followed.

Otherwise your options are to shoot or live trap them. I would just patrol around the property and shoot them as I see them. You can try staking out chicken coops or whatever they are hitting but I'm not sure if that would work too well.

I'll post more when I get off work.
