The Colorado rules say once your animal has been 'processed' it must still meet evidence of sex requirements. Obviously, if commercially processed there is just no way to no what it is. In this case, benefit goes to the hunter who is doing his best to take the best care of his meat possible. If not commercially processed; say, if cut and wrapped in camp, then evidence of sex should still remain with a large cut of the hind quarter. Unless a Colorado GW suspects a crime they usually won't hassle you. Now, for instance, if evidence of sex is cut and left in the woods then standard operating procedure is to issue a citation for EOS, take a sample of meat for DNA analysis. If DNA shows it is the wrong sex, someone will come visit about illegal possession.
