Here in NC it is legal to hunt 'em on Wed, Fri, and Sat. I have never had much luck with an owl decoy round here.
I do have a mounted bobcat and coon the works pretty good with a flapping decoy under the front of it. A house cat in a harness works good too. Harness better be tighter than you think it should be though. Lost my step-moms cat that way.
There used to be a crowbusters.com that had small flapping crow decoys that work great and were cheap. Don't even know if them guys are still around. Gonna look and see.
Going after a few crows saturday morning.
God Bless, Louis
