I have hunted the Delaware's in west TX the last 12 years. In the last 3 years the Aoudad population has jumped quite a bit on the place I hunt. It is just over 60K acres total. This ranch has just about everything but whitetails and hogs. If you jump a mule deer he will move over the next hill and stop. These aoudad will not stop until they are in the next state. Once they start moving they are gone. So you better be ready to shoot. This is some rough country so be ready to walk miles at 4000ft+ elevations.
