Fox you can always trap or shoot. Hawks....usually illegal to shoot at least where I'm at. You could try putting some Owl decoys out or some pie tins tied on a pole. They don't like the noise or the shine they give off. A dog works the best. Mine is out when ever the flock is free ranging. Don't know if the previous techniques actually work but I have both. I feel that it's some sort of safety attempt at least.
for the hawk read the instructions on the permit form they will tell you what legally can be done according to federal law http://www.fws.gov/forms/3-200-13.pdf for fox I just trap and dispatch them
