One of my neighbors is having difficulty with turkeys coming into his yard and scratching it up at night. He knows that they are turkeys because he has gone out a couple of times at night and run 'em off.

I suspect that they will eventually leave on their own, but untill then, does anyone know how to keep 'em away?

It's not like it's just a bird or two...It's closer to twenty or more.

His yard is about ten acres and on the side of a ridge with plenty of embankments.

Thanks.
