Yes you will need a permit if you are raising BobWhite, Scaled, or Ringneck pheasant since those are the recognized game birds here. Oklahoma has two different permits, one for non-commercial game breeders (raising for your own use) and a commercial game breeders permit (for selling birds). The non-commercial breeders permit is $25.00/year (I don't know the cost for the commercial permit). They may have something listed about it on their web page
www.wildlifedepartment.com or at least they will have the phone number to call them.
