Those deer are tame. The guy who's pasture you saw them in has raised them from fawns. They don't even know they can jump the fence. But I agree, they will make some interesting fawns if they figure things out. How does he get away with raising them in captivity is my question. 
not sure what the laws are up there but on a visit to my dads gf's brother in mighigan they drove me past a guys farm that had a heard of albino whitetails (said he had zooalogic permits) also said he'd been doing it for years and once in the past some peta tree huggers cut his fences while he was away on vacation. I guess the plus side to that would be some odd ball trophy genes running around in the woods in the area.
