Yep, Just becuase he has it, doesnt mean hes aloud to and he would probably get it trouble if he was caught with it, even if he did save its live. Llamas and Buffalo (Bison) are the only hoofed exotic animals that our Georgia DNR does not regulate. and quoteing a Ga. Market Bulletin
" However , upon compliance with applicable state regulations, a deer farming licence for commercial production of meat and fiber is avaiable for the following species: Fallow deer, Axis Deer, Sika Deer, Elk, Red Deer, Reindeer, and Caribou "
So thats not saying that these animals can be kept as pets and it also does not include our local native deer species, The Whitetail Deer.
And with with migratory waterfowl, I have heard two different things, I have heard that they are not legal at all and white Ga.'s laws, I wouldnt be suprised, and I have also heard that they are legal to own, but but must have a permit to sell/give away/or otherwise dispose of the birds. And they still cannot be taken live out of their natural wild habitat, they must be bought from someone with a license as well. Bobwhite Quail here are the same way, a permit is required for selling them since they are a native species here. Mallard Ducks must 'legally' be 3 generations from the wild to be sold.
But like I said, Ga. is about the most restrictive state that I know of and it varys from state to state so you should call or email your states DNR for the details for you.
