We had this happen several years ago, my husband's grandmother sias weaels, a ferret turned loose, she named off several critters. We set the live trap up, wired a piece of chicken in there and caught what HAD to be the oldest, roughest looking hoot owl we have ever seen! He'd pop their heads off and rinse and repeat the next night.
We relocated him down to a more rural part of the river and told his Grandma ... she got after us because apparently back in her younger years, hoot owls made darn good dumplins. She said we just didn't know what was good!
Not to mention, the owl is protected lol.
