A couple of thoughts here. Too bad you didnt mount it, as a skull with antlers could be a doe or buck, you wouldnt know as well, the differences are so subtle. Regardless, most of us do not boil skulls, it breaks them down. Anyone who boils will reply Im wrong...until the day come when they finally have one crack, fall apart, etc. Russian roulette! No thanks, lol. Anyway, Id send it to get beetle treated if it were me, and whether you boil or beetle it, youll first have to address the velvet antler. Sometimes the antler velvet and the antler itself can just be dried out, especially on the does with antlers, as its not always as mature an antler as a buck. Id cut them off, have them dried and treated, or better yet, freeze dried, and when the skull is finished, pin the antlers back on. Thats the best way, but Im sure youll hear other methods. Boiling or beetles WILL effect the velvet, either way you look at it...
