thats photoshoped-

Deer do get that big-rarely in nature it takes specific breeding and nutrition i.e game ranches-its no different than any cattle producer

You can tell by the face of the buck-a rack like that is HEAVY-if real his neck would be much thicker and that is a rack of a matured buck-the photo of this buck looks young.

As for ever seeing a buck like this-nah but i would not let him stand around long
