Yep, I like to use them for practice myself. It is pretty hard to remember which days of which months and the shooting hours you're allowed to shoot them though. Since your From Ohio you'll be able to understand all that.

We have a season in Ok. also because of the migratory bird treaty with Mexico, since ravens sometimes fly with crows and ravens are protected in Mexico. We can shoot them anytime if they are harming land or crops, I figure that means if they are flying over doesn't it?
