Found a site here with Animal Laws for all 50 States. http://animallaw.info/ Here I discovered that only some Migratory Birds have full protection here in Oklahoma. It is Legal to kill Hawks and Owls that are killing your chickens. NOTE: Eagles and Falcons are still protected. You might want to check your state to see what is Legal and what isn't.
